does anybody know the thickness of the wood blocks between the body and frame on a 1929 model a coupe?
Not sure of thickness but you can get a set for $29 from Bert's model "A" center in Denver,CO. www.MODELASTORE.com is their site.
I just got a kit for my 29 P/U. Some pieces measure 1" and others are 1 1/4" thick. Unfortunately, I forgot to bring my diagram (which tells which ones go where, on which model, etc.) to work to be able to tell you which ones go on your coupe... PM me and I'll look it up tomorrow and try to get back with you...
Here you go...sorry for the delay. The first pic tells you which block goes where depending on whether your 29 is a P/U, Sedan, etc... I just got this kit from Mac's for my 29 closed cab P/U. The blocks on the left measure 1 1/4". The blocks in the middle measure 1 1/4" also, however where they're milled top and bottom, that portion measures at 1". The blocks on the left measure just a smidge over 1" (smidge is another word for about 1/16", give or take...) I know you were asking about your sedan, but I'm hoping this might give you a baseline to start from. Hope this helps...
