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

FYI - Your post is interesting. The answer is out there, members on the fourm will answer Im sure. Here is the hood on my 29 Ply Coupe. Rich

A follow up to this thread, the headlight bucket wire harness connectors arrived and now I have a few extra sets if any forum members need them. For two connectors my cost with shipping $20.00. PM address if interested. - Rich

CHET - If they are the right ones ,it looks as there is one extra so will let you know when they arrive. Rich

I think I may have found some connector retainers we have been discussing. Just found and ordered them today. Won't know for sure until they get here but they look like they will work. If so there will be a few spares if anyone is in need. (at cost only plus a little shipping to members on this forum) see photo. - Rich

Just a thought. The connector retainer you show is reduced in diameter on one end maybe to accept some decorative flexible metal tube. What do you think? - Rich

Now that I had a headlight connector photo to refer to, went digging in the box of leftover wiring harness wires and came up with a version of the retainer that was on my car. (See photo). A little different on the end but looks like either version would work. At least down to one more connector retainer to find. Thanks all, Happy Motoring - Rich

I don't have a spark plug tube but will keep an eye out. Good luck. Rich

  Russ T Fender !! That is the connector view that I needed. The black three wire plug is orianted into the metal sleeve that is in your photo by the narrow slot down the outside of it. The metal sleeve connector with the the black three wire plug inserted pushes into the Depress Beam bucket and twist locks in place with the two pins on the outside diameter. Thank you for the photo. Now it all comes together.
Just to explain a little. My 29 Ply has been disassembled this past year to get ready to paint. The headlights and mounting bar were stored in a safe place. I went to retrieve then to work on and they are no where to be found. SO!!- I have found a replacement mounting bar on EBay and a set of headlights but they are not as good condition.  Anyway the reason I didn't have any thing to go by on the wiring. The buckets are a little rough but they did have both the bulb connectors in each one. I had to rewire them but needed the photo you furnished to see the sleeve they need.
If anyone has a couple of the sleeves to sell or know of a supplier To buy them please send details.
Thanks again Rich

Thanks for the reply. I did see that these were available. The connectors I am looking for are the ones that plug into the connector you show that comes down out of the headlight bucket. The one in your photo in the upper right corner. I was hoping for a photo of the connection of the harness into the headlight bucket. Not sure what that connection looks like unplugged.  Thanks Rich

can someone supply a photo or the harness connector that plugs the harness into the bucket on Depress Beam system? I have the three wire plug on the end of the harness (see photo below) but need two of the connectors to orient the three wires into the bucket. I don't know what they look like. Tried to find a supplier to purchase them with no luck. The connector coming out of the bucket is made to receive two pins like a lightbulb. http://www.1948plymouth.info/28Q29U/index.php?action=dlattach;topic=959.0;attach=3576;image for any help Rich

Chris - Thanks for the spare parts. They arrived Friday. Have not had a chance to work with them as yet. Will keep you updated. -  Rich

Just a few details picked up while trying to get all the parts necessary to complete an ignition switch and coil that matches an original for my '29 U Plymouth.

As the '29 Ply. U has a mechanical gas gauge in the gas tank, the correct ignition coil only has two terminals. One for hot wire and one for distributor. The coils that have three terminals are for cars with a electric gas gauge at the dash. That terminal is usually marked (GAS OR FUEL)

The dash faceplate on the '29 U Ply is oblong with rounded corners. The DeSoto faceplate is styled the same but has a  raised point in the top of the plate. It might have a gas gauge at the dash.

An interesting piece of info I came across is someone mentioned the battery terminal on his coil lost contact so he connected the wire to the gas gauge terminal and got it home.

Thanks to the forum I'm waiting on some pieces and parts to try to put together a key switch and coil the next rainy day that comes by. More details later. - Rich

Congrats! Won't be long now.

Chris - Sorry for the reply delay. Have been out of town visiting family. I found a coil/switch combination but it is for a 1931 Dodge. The face plate is different but the round pot metal part looks to be in good condition and it came with a key. Haven't had a chance to take it apart to see what condition it is in and see if I need any of your spare pieces. (if it is the same) Being they are hard to come by thought it worth a try. For now, thanks for helping. - Rich.  PM to follow
