This is what's in the front now, so I guess I'm going to need one of those parts anyway. My plans are rapidly turning to pulling it into the garage (my girlfriend has told me that she'd use the small garage giving me the 2 car garage for the work on the '40) and strip it down to the frame and go from there. I've already begun making a spread sheet of the parts I'm going to need and the prices at different suppliers. While I was originally leave the '53 235 in it and try and figure out what the rear end was I am now thinking about finding a 283 or 327 and seeing what it would cost to put in a Mustang II independent front suspension and a 4 link rear suspension. I don't know if I'd need to box the frame with the 283 or 327 so some research is in order. It looks like most of the parts I need are available except that rear floor, but how hard can it be to fabricate?
