On the 29 4door Sedan does anyone know it there is a usable rear window gasket available or material that would work. My car had nothing and the rear window was held in place with some type of putty.
Also was there specific interior rear window moldings or will a simple wooden window trim suffice ? Maybe upholstered 1/4" trim pieces ?
Any thoughts appreciated.
Tks Chet...
I am still using the original gasket. There is an inside metal trim piece. A little difficult to see, but best I have.
Frank, What year is your car. My rear window moldings are different. They are the same as Dave's car.
1929, Chet, according to FEDCO number. Has the same tin nailed to wooden frame as yours, not like the metal 1930U.
Anyone have any experience replacing the rear window in the sedan. ?
Is it just black silicon RTV ?? Any advise ?
Does Steele Rubber have any thing that could be modified fit?

I looked but the glass is a rectangle so I think it would have to be made exact. I'm not exactly sure what to even look for. My 48's glass was oval and you could wrap a seal around it but hard to make the corners of a small rectangle.
Do you have a rubber gasket ?
Yes, the original looks like rubber to me. If you had a rectangle rubber in larger than dimensions, it could be sectioned vertically and/or horizontally to fit and secured with rubber cement?
Interesting idea.
Check e-bay Double Sided Butyl tape for glazing . All sizes and prices vary .
This might be a possibility for a rear window seal I found on EBay. 1/8" Rubber Edge Trim HR70J SOLD BY THE FOOT in Black U Channel EPDM Search item #223331810775. There is a lot of versions to look at. Rich
Thanks Rich & Tom,
I am looking at all these items just trying to see which might be best. For the rear window you need a right angle type gasket or use the Double Sided Butyl tape that Tom recommends. I think the latter might be the solution but I am still searching around. Somebody must have had to replace this window. I am looking for some words of wisdom from someone who has been there and done this. If that doesn't work out, I'll try to choose a solution, wisely.
Chet... :-\
Chet , do a search on AACA on butyl + window . Some great dissusions on round vs flat vs newer urethane .Also cleaner and existing .
Review the picture below:
(http://www.1948plymouth.info/1929/images/Build/RearWindow-01.jpg)
The detent shown in the picture on the right is found in the red circled areas in the picture on the left.
I believe these 4 detents are used to position the glass and also keep it from lying directly on the metal frame. With that being said I believe that originally some type of glazing compound was used to seal the window to the frame of the body. I don't believe any gasket was used. What do you guys think.
I am thinking flat Double Sided Butyl tape might do the trick if it is reasonably soft and malleable. I have never used this tape before so I am not sure. Any thoughts.
Chet
I am have trouble visualizing where glass goes . Your close up is to close . Is that metal going to touch the glass or back up the tape holding it in some how ? Did you remove any sealant ?
To me sealant should go against exterior metal to waterproof . Then glass , then maybe fold over or and more seal , then something ie. metal clips or tabs to keep from sagging or popping lose . But never metal to glass .
Exactly Tom, Now you understand my dilemma.
dilemma
1. a situation requiring a choice between equally undesirable alternatives.
We are on the same page...??
It looks like these detents force the glass to center. On second look there isn't much of a bottom one.., only the two side ones are like the picture. The top one isn't as pronounced and the bottom one is very slight. Maybe they square the glass against the rear surface. Maybe there were clips that went behind these to tighten the glass or some type of molding. Maybe tightening caused them to bow out ?? That's why I am asking if anybody has changed this rear glass and what and how they did it. (Might need additional parts)
It seems like this glass was held in place by some type of glazing putty rather than a gasket. Of course after 90+ years who knows what happened to this area. Maybe a farmer used plumbers putty to set the glass. ? ? ? ? ? ? ?
BUT; the window is original glass not safety glass. I will have a new window made up with safety glass, also going to replace the windshield since I have already replaced all the door glass with safety glass.
Eventually I may get it right the second and third time...
OK Tom.., I used the double sided glazing tape to install the rear window. The exterior looks good with a nice 3/16" of glazing tape making a nice even exterior window seal.
Now I have set the glass does this stuff harden or does it stay soft. I have never used this Butyl tape before ?
BTW.., The raised areas were not an issue. I put the tape all around the frame and pressed it level before installing the glass. It made a nice even seal.

I am not sure on how it hard exposed to sunlight . We use it underground to seal concert vaults . But on window I've seen it must skin over for cleaning . I do not think it ever hardens , maybe firms .
How was it working with ? Seem to have molded in nice . And what did you come up with to back up holding it in position .? Did you use something on the clips ?
Tom,
I think I will frame the inside like a regular window. I could simulate something in wood and paint it black like the other window moldings. Or maybe upholstery the wood. I have pictures of Dave's car and he has upholstered frame. We'll see.
I thought you have used this on glass.
OK guess I don't understand the problem here - why not use the rear window gasket for a model A sedan - the window is bigger than the Plymouth so you have lots of rubber to work with. it goes right in over the body channel opening for the glass just like the original. a little windshield sealant seals the ends (black). Set the glass in the bottom channel of the rubber then with a little pressure and a string you roll the outer lip over the glass -DONE. seems better than glazing strips or whatever......I know, don't use model a stuff on a Plymouth but ya gotta use whats available sometimes

This post would have been nice if received earlier. I was asking if there was a useable gasket I could modify and use. Which Model A part should I order. ??
Tks Chet...
go to Amazon - search for Trim Lok dense rubber window lock gasket - P# LK1663-25
rwollman,
I hope the picture I made will help explain the problem. There is no flange to mount a rubber gasket and the body is at a right angle to the glass and is nailed to the wood frame. I have the Trim Lock catalog and I really didn't see anything that appeared to solve my problem.

To complicate matters there are also 4 detents that appear to help position the glass. see below:

Have you replaced the rear window in the 29 sedan. Did the Model A gasket work out OK. Also how does the Model A rear glass work. Is there a flange or a thick right angle like the Plymouth's body.
Thanks, Chet...
Looks good Chet . I think you did not have much choice on methods . Only option was maybe type of sealant and for every good to be said for one, you'll find two bad's . They would not have had urethane or rtv or butyl , so must have used something petroleum based mastic / tar . The main thing is your backing up for sag and it looks good and keeps water out .
Sounds like your confident in all those parameters .
Tom,
I guess this stuff will work OK. It has pretty well set itself into place and the window won't budge. After the frame is installed it should be fine. The tape I used is "CRL 3/16" x 3/8" Double Sided Glazing Tape - Butyl Tape Black Used for windows and RV's" I read a review from a guy who set in a window on his boat and it worked fine with no leaks. He said he might have to break the glass to remove it again. Who knows, but it seems to be fine. I doubt if this car will ever see a hard rain but I am confident the window won't leak, move, or crack. Now whether it will last another 90 years.., well only time will tell.
Sorry - the 28 just has a flange that the rubber sits in, then the glass goes in outside groove of rubber.. no detents on the 28 that I remember. Had the gentleman that painted the car install just the seal, that way if any cement (sealer) got on paint he could remove it - I just put the glass in. Hard to believe they would change that much in one year unless the two body manufacturers did things a little different in some areas. I believe u already have your glass installed?? . I'll look around a little and see if I can come up with something now that I know what you are dealing with..
That's great. Always good to have choices if something doesn't work out. Frank has a 29 sedan and his rear window moldings are different than Dave's and my car. I have been using Dave's car as a standard in that it is an unrestored survivor. Each of these cars seem to have their own story.
