I believe that is also why so many of them are cracked.

I have not resilvered any reflectors and probably never will as I don't do much night driving and all but one of my other cars have gas lamps so I am used to marginal lighting.  There are a number of outfits that will do it and a lot of people are opting for Ulvira (sp?) instead which is an aluminum base covered with glass.  It's pricy but I guess you never need to polish them or deal with the issue again.  I have seen the results and I was very impressed.

The more I think about it, I might actually have two buckets down in Florida. It's been a long time since I last dealt with the headlights and my memory is not what it used to be.  In any event it would be a good idea if I had your dimensions and pictures so I can match them up against what I have.  I know all the reflectors need to be silvered ( even the ones I am using now ) and the wiring is toast and  I can't remember if the bezels are there or, if they are, what shape they are in.
I hope to be back in Florida no later than January 15 and will touch base with you then.

So far I have been able to find out that the shape of the bucket is the same as the 30-U but the lamps for '29 and '30 have different parts numbers.  I believe they have different part numbers because your lamps are chrome and mine are painted. In any event I think the single lamp you found is the right one for your car and it may also be that your lamp bucket is brass, not steel like the 30-U although either can be plated.  There may be a difference in the mounting too but from your picture I think the lamp you have looks to have the same mounting set up as my car.

That would be good but I wish someone had the information we need to determine if the lamps are the same for both years with the exception of the chrome plating.  I have been searching for period photos to try and figure it out but they are few and far between and the few I have found don't show the headlights well. I will try to contact the new Plymouth Owners Club technical advisor who took over for Bob McMulkin and see if he can help.

I have a spare bucket in Florida.  I'll check when I get down there after the New Year. It's painted but could be chromed if you can't find another one. Of course that assumes the 30-U bucket is the same as yours but I'm pretty sure they are.  Does anyone know for sure?

I am almost positive that the tear drop headlights you have on your car are not correct.  I think the shape of the headlamp you show in your post is correct at least in shape if not in size.  They are out there.  I saw a pair at Hershey last year that were better than the ones on my car but I passed them up as they were all chrome and I had just painted the shells on mine.  Big mistake in retrospect but certainly not the first one I've made.  The other issue is that cars with cowl lamps have a two contact set up while those without cowl lamps have the parking light integral with the headlamp and have a three contact set up.

My 30-U has depress beam headlights.  The buckets look the same but they are painted not chromed.  Don't know what the lens size is and the car is 1200 miles away from where I am now so I can't check that.attach id=6288]D25CAAA6-5D2D-4499-88EA-80E9C79D609F.jpeg[/attach]

I thought both the '28 and '29 had the Plymouth logo on the shell but the '28 logo was blue while the '29 was black. From your picture the logo on your shell looks black so that should be the right one.

I'm thinking there is a big difference between the way your radiator sits and the way it is on the 30-U. This is my crossmember and all it has are the holes to accept the studs shown on Chet's picture.  There would be no reason for the holes on your radiator frame. Does your cross member have the rivets that require those holes? If not then perhaps you have the wrong radiator for your car.  Right now I have to admit that I'm as confused as you are.You cannot view this attachment.   

That is how the radiator on my 30-U is mounted.  The bolts that go through the cross member are welded to the frame of the radiator that surrounds the core.

The way the frame around the core is set on my car once it is bolted firmly in place it can't move so I don't think there is any reason for a pad.  That is unlike the way the radiator is mounted on my Model Ts where the radiator is supposed to be able to move a bit to compensate for the flexing of the frame so a leather pad is required.  That said, I think a small, very thin rubber pad, or better yet a bit of thin body welting, on each side where the bolt goes through to the cross member wouldn't hurt but I think you definitely want to avoid any movement down there. I bought my car from the original owner then drove it for 10 years without any radiator issues and when I removed the radiator during the restoration there wasn't anything there.  I can't swear that there wasn't something there from the factory but I think not. 

On my 30-U there is nothing between the radiator mount and cross member. 

Yes those are the ones I saw. Are you still looking for two more?

There is a guy on eBay with 2 for sale.  Check under 1930 Plymouth.  I would give you the information but my computer skills are poor at best.  There are a lot of variations of these caps as there were a lot of after market replacements made to compensate for the dreaded curb rash.  They are close enough that the differences are negligable
