Thread: Another 700R4 Question

Tweet

Can't help much because I have a Brookville repro frame under a replica '29 body. I can tell you that I started with a TH350 and then decided to use a 700R4 and I had to change the Brookville sling mount under the trans to mount the trans bolts about 3" further back so the bolts are further back. Fortunately, I had not yet set up the drive shaft, so the drive shaft set up for a TH350 may not be the right length for the 700R4, assuming the motor mounts are in the same place. In the Brookville frame the brake pedal and the master cylinder do clear the side of the 700R4 by at least 1" but it is tight on the driver's side. I do have a large vacuum can for power brakes on the master cylinder and that clears OK too. As I recall the stock Model A frame there is a "hat" cross section cross member somewhere in there but the Brookville frame just has a rectangular tubing 3"x1" crossmember at about the same place and the trans sling hangs from that. I am attaching a drawing of the original A frame but the whole problem depends on where your motot mounts are. I had to make the diagram small to get it on here but you can expand it with Paint.
