BOP Bell fit really well so far. I have an idea for reusing the repo master I bought for the original brakes. I am using the power brakes from the 87 donor truck. Pedal off the dash/firewall.
What if I connect the rod end to the 49 clutch pedal linkage instead of the old brake? Then connect a slave to the clutch with mounts/linkage off the bell some how?
Linkages , column position, motor position , pedal position I have to get the fully dressed motor here to really check things over.
I might be able to get away with just mounting my spare heads to the mock up block.

manual trans compare pic looks like same bolt pattern as sm420, but spline and shaft are way smaller.
