Chet,   the pictures are from Dave's car and measurements from mine. (platypus)

Chet disregard previous post - that is rear window!

Side window, I have 3".   I'd still poll John, Dave

Chet, mine looks to be from 3 1/2 to 3 5/8".  You may want to get a number from John &/or Dave for something original.

Pictures of Dave's car.

I have the same issue, but have not removed the door or kick panels to inspect.   29 and 30 appear to be the same.   frank

Chet, Fantastic work!!

Chet,

Was looking for info for Dave.  He is taking his out to replace glass and it doesn't go up/down properly.  I removed mine to put in safety glass a few years before the article and my memory is very sketchy.  I didn't remember removing the dash, but who knows.

Thanks, John.   Time flies, would not have guessed it was 15 years ago.  frank

Hi folks,

Anyone remember which Plymouth Bulletin had a good article on removing the windshield?

Thanks,
frank

Nice Chet!  Just remember this is not a high falutin Chrysler!

I believe kimmc used 2 part epoxy with sawdust as a filler.  Bondo in thin layers to fill holes and cracks?

Chet-my sedan Kingston tank has no vacuum relief and works just fine.  I have seen it on Stewart tanks.

Rwollam-by looking at Chet's picture, the cork diameter is probably about 1.5" or so.  Interestingly my cork has not been replaced or coated since I've owned the car, 1965.  i 've been told corks can be coated with "DOPE" paint from a hobby store.  This was/is used on gas/alcohol engine model airplanes.
Your brass float may be in the wrong location on the shaft allowing the gas level to rise to high.  I had this problem when the top cork stay solder failed and the corks slid up the shaft.

good luck,
frank

(now I need a Kingston for the roadster)

Saw this today, Plymouth Otwell Heater manifold for sale on ebray.
