ok. wait a sec..... If you already have a bad TOB AND the half-axle & intake plenum mounting bolt threads are FUBAR, why don't you just pull the engine to take care of everything at the same time:
A) swap in a decent clutch (as previously mentioned) & new TOB
B) Drill, tap, and heli-coil the half-axle mounting bolt holes in the block with it OUTside of the car.
C) Drill, tap, and heli-coil the intake plenum brace mounting hole in the block with it OUTside of the car.
D) Replace any leaking gaskets with the motor out of the car.
E) Don't worry about the head just yet you can tackle that another time as it's easily removed from up top anyways.
-90* drills??!! With the car on a rack MAYBE but up on jackstands? -Bolt extraction combined with poor angles, PLUS hot metal shavings falling on you isn't my idea of fun. I'd just say F it and pull the motor, refresh what you can and save time and keep from repeating yourself in the process.
