Just picked up a 1960 Belair 2 door this week. Have been looking for '59 or '60 Chevy for a while now. The original cast iron PG crapped out so the guy started swapping it out for a later aluminum glide. The trans is in the car but the job is incomplete. Looks like he though it'd be a simple swap but didn't work out that way. Trying to figure out everything that won't match up. So far searching I found the yoke won't match, believe it's the same as the TH350 on the newer PG. The starter isn't a problem, it's not the original block so there are starter mounting holes. Looking under the car the cooler lines come in at a different angle, side versus back so some rerouting there. He put the flexplate and torque converter from the later PG on the motor but it looks like the bolts are too long. They stick out the back of the crank and are actually touching the seal/block. Guessing those have to go as well unless the original flexplate can still be used. Anything else I'm still missing here? Right now I'm just trying to get it moving under its own power so I can get it in and out of the shop as needed. Haven't decided on a drivetrain yet, since it's not the original block I'm not too concerned about swapping in something else.
