Having problems with installing a new top on my 31 Roadster. I purchased the new top from Mike at Classtique Upholstery. All went well until I tried to fit the Main Top Deck to the car and discovered that it is about 4" too narrow. I didn't realize when I ordered the top that, according to the Model A judging standards, the Canadian built cars did not change to the newer style US top frame in early 1929 but continued with the early type top frame throughout production. I have talked to Mike and he is being very helpful but it seems that the only way to get the proper components for my top is to identify which of the 3 early types of frames were used on my 31 Canadian Standard Roadster. Mike has the Ford patterns for each of the frames but needs to know which of the 3 frames I have. The only info he has with the patterns is the Ford part numbers for each frame.
Early 28 A-42175-AR
Late 28-early 29 A-42175-BR
Late 29 A42175-DR
There are no part numbers on my frame. Does anyone know a source for the meaurements for each of these frames and/or any identifying features that would help me identify which of these frame migh be on my car so I can order the correct components to replace the ones that don't fit. Any help would be appreciated.
