Ayuh,... What's the issue you're having with the fitment anyways,..??

Chevy's have always used 2 different flywheels,... 12", 153 tooth,+ 14", 168 tooth,....
Then of course there are 2 more of the same, but smaller bolt patterns for the change in crankshafts in 86/87....

Ayuh,... It should be available...

Does the 168T clear the flywheel cover,..??
Will the Volvo coupler bolt to it,..??
What does Volvo use on those drives,..?? Flex plate style, or rubber coupler style,..??

Ayuh,... You need the 153T with the 3" bolt pattern....

Call your local Government Motors Dealer...
