33/34 ply roadster info in Plymouth Posted February 21, 2015 As I indicated in my private reply and as ply33 indicates, foreign Plymouths only for 33 and 34 roadsters. The ones in the states are 'convertible coupes' like my 34 PE or Chris in Texas 33, roll up windows like what the Ford guys call a cabriolet. Plymouths (and Dodges) convertible coupes do have a fold down windshield like a roadster, unlike most other cabriolets, where the windshield pillar is an extension of the body sheet metal. I have attached two of the few pictures I have of a Plymouth roadster, I believe this is a 34 Australian version. If you look at the top bows (and I am assuming these are originals, I don't know), there is no true 'B' pillar like in the convertible coupes (which is needed for the window frame to roll up against), the pivot point being further to the rear of the car. The third picture is my 34 convertible coupe, so you can see the difference. In short, the top bows would not interchange. None of my part books show any roadster parts so no help there. Good luck on finding a set of those unless you can hunt in Australia. I would suggest you contact someone 'down under'. 33-34 convertible coupe top bows are nearly impossible to find and I would wager that roadster top bows ARE impossible to find. Post some pictures!!
