Rick--I have high regard for you guys that wrench for a living.
My FIL and I have been working on the hotrod Z28 this week trying to find a rattle/clunk/thunk type noise. We've narrowed it down to a cracked flex plate so we are pulling the trans out to inspect the bolts and check for cracks.
What a total PIA!!!! Even with a lift, getting to the bellhousing bolts are absolfrikkinlutely torture.
I spent about 4 hours under the car today and am feeling it now. Still have one stubborn bolt to remove and you can't get a socket on it so I have been reduced to using a wrench that I can about turn about 2mm each stroke.
If the flexplate isn't cracked I may bash it with a hammer just so it was worth getting at it.
