I've been working on mocking up my seat and accelerator location, and welding up holes in the cab. But since I don't have any pics, I'll post a couple of pics that I DO have. Taking a slight detour from the cab, I am shrinking the size of my steering wheel. I want to keep the original center, but since the wheel is so large (18" I think) I am hybridizing it with a 15" rim. I believe the 15" wheel came out of an early '70's ford.
I have the center of the smaller wheel cut out and I will be welding the original center to the "new rim". Per one of Old Sarge's old posts, I will use epoxy to fill in the gaps. I'll post more pics as I progress.
