NOTE : Pontiac engines had 2 different crankshaft registers, a 2.5" and a 2.75" register.  The register is what centers the flywheel on the crankshaft, but the bolt pattern for the flywheel is also different.  Typically, 75 and older is 2.75", 76 and newer is 2.50", but that is not always the case! YOU MUST MEASURE YOUR REGISTER PRIOR TO ORDERING TO ENSURE YOU ORDER THE PROPER FLYWHEEL!
