I still have one bellhousing for an 1978-88 A/G body left. It's #462606 and has the Chevy bolt pattern. It still has the original A/G body specific clutch fork attached. There are no cracks or broken bolts. It's dirty but will clean up nicely. $85 plus shipping.

 

The bent throw out bearing fork is probably worth $85 by itself. GLWS

 

Put it for sale on the G-body forum. Start at $100, "packaging fee." (:•》
