Ahhh yes, I ended up mounting my prop valve off the master cylinder studs/bolts. I used my line lock setup for my "T" for the front lines, and used a block union for my rear lines. the block union I mounted about 12" more towards the rear of the car on the frame rail to clear my TTI's. As for the steering coupler I used a stainless u-joint style coupler from sweet manufacturing. I got it from speedway motors about 7 years ago now, still works like a champ. For manual steering boxes If i remember right its 36 spline, and the sector shaft I machined it for 3/4" double D from the original 3/4" single D face, after cutting about an inch off. worked perfect.
