American Powertrain Hydramax install?

No worries, I know the feeling. I ended up fabbing up my own setup based on some other installs here. It's not as pretty, but probably more structurally sound than relying on the firewall alone for support. I welded a tab to the side of the main pedal support or something like that where the brake master cylinder/booster mounts. That way all the pressure is being more evenly spaced out over thicker metal. I had to flatten the firewall some to make it work though, so it's not really pretty and not something I'd want to do with a valuable car as it's not exactly the most reversible option. Overall my pedal feel is okay and seems to function fine with my T56, though it's not as "clean" feeling as a clutch in a modern car. I'm sure I could tune the geometry better, though some of that could just be my clutch setup as well. I originally started with a 3 finger style pressure plate, but swapped over to a diaphragm style after finding out I had a cracked finger that was keeping the clutch from fully releasing. I think some of my perceived issues are tune based as well. I used to think the clutch released somewhat non-linear since it seemed like there was a point in the travel that would really bog the engine hard in very little pedal movement, but after playing with the tune I've got it more sorted out where that is less noticeable and it's a smoother engagement.
