Actually there are a couple of us who have early 30 Plymouth tin. Unfortunately I know nothing of rod shops in MO. Know some in PA and Md who could help, but they are many miles away from you. I have a 34 Plymouth 2dr sdn street rod with a sbc and a th400 trans, M2 IFS and a 'Vette IRS. Other than the body and frame, not much Plymouth left. Plymouth boxed most of their own frames in '34, so I didn't have that problem. Floor is custom made from stainless steel, gas tank is custom aluminum. Dash is a Wabbit with Classic Instruments, interior is all custom with buckets up front and a contoured bench in the rear. So as you can see, the car is an all steel Plymouth, but nearly every thing else came from someplace else. And I think that is what you will find in most early (pre-35) Plymouth and Dodge street rods.

There are several places dealing in parts for early Mopars but mostly NOS or replacement parts. Ply-Do out of Delbarton, WVa does have some hot rod parts as well as restoration parts. But you are pretty much on your own.

I have a friend who is a rod builder who has a 34 ply coupe, could put you in touch with him if you need some specifics. Overall. they are just cars of a different brand, still relatively easy to rod if you got the time, patience and money, which is required even with a Ford or a Chevy.

Good luck with your rod. They really are nice rides when done.
