am in the middle of it now, cab is off. ended up making my own mounts. using some thru bolt donuts from Speedway.Didn't want to cut out the steering brace in the frame.could have modified some small block mounts if I had. made the rear crossmember too. am using a '58 315 hemi from a truck and the 4speed from the same unit. offset it 2"to get some steering gear clearance. am going to recess the firewall about an inch, that will put the back of the transmission where the old one was. using the original clutch pedal and making a brake pedal and moving the master cyl behind the pedal .using an 8 3/4 Mopar rear out of a 73 pickup so the old wheels will fit.
