WOW!! You cut that real close to disaster. Glad you cought it. Good luck with your little built up too.

 

take a chesile and and hammer.
go in between the flex plate and crank shaft, work it all the way around
it will come off

 

and uf that dont work get a small die grinder and cut it on both sided from the center tot eh top WITHOUT GETTING IN TO THE CRANK!!

then you should beabel to hit it with a hammer and it will fall off for ya that way also

 

When I went to unbolt the engine from the transmission, two bell housing bolts weren't even hand tight and one was missing. That would probably be why it cracked in the first place.

Anyway, my dad and I worked at it for a little while and the remains finally came off. Tapping it with a hammer (not slamming it) and a prybar with some WD-40 and it slid off. I'm surprised that the plate didn't fly apart in that condition.

 

GM back then had a problem with the flex plates cracking.
I would say that the trans bolts are a result after the flex plate breaking causing a vibration.

 

This wasn't the stock 31 year old flexplate though. This was a 3 1/2-year old plate with almost 50,000 miles on it. I think the flexplate cracked because the bell housing bolts weren't tight.
