4 speed identification

Thanks for the information, 66fs. I think it clears up some of this. You're right, I probably should have started a new thread, but the first question in my mind was one of identification. The rest of it is the result of asking one question generates more questions syndrome. For example, under what conditions will the 9.5" clutch become overpowered, cruising or race?

I'm working on getting another '75 cast iron OD trans that looks a whole lot more complete, including shifter w/ black knob and rearward sweep. That one may not work well with my bench seat, but I'll be getting some sort of bucket in the future. It means a 7-hour one-way trip up to British Columbia, but I've always liked Canada and could use the road trip. I'm waiting for his response.

The motor is a '66. I'm not sure if it has room for a pilot. There is a recess in the crank flange: ~ 11/16 deep by 1 13/16" in diameter, with an ~1/4" collar protruding from the crank flange surface. See pics below.

I'll probably go w/ new Shumacher mounts and brackets (after I get done convulsing over the price). In the mean time I'll be searching for a set of brackets.

I checked out the tunnel hump in Classifieds. $125 and it looks like it was modified from another application. Brewer's has new, proper-fit fiberglass for $130 plus shipping. Seems like a better option.

I'll look on the 4-speed forum to see if I can find out which parts I need for the BH.
