Do 66-72 BOP A bodies use the same u joint at the rear? If not, what is the difference? Thanks

 

I know there is a difference between the 8.2" 10 bolt's ujoint and the larger 8.5" 10 bolt's ujoint.

when changing a rear but keeping a driveshaft, sometimes a conversion ujoint is used that has both sizes. For example when upgrading from an 8.2" rear to an 8.5" rear.

 

Thanks, where is such a conversion u joint available?

 

NAPA has a good Ujoint with the crossover .
