I have a 1980 chevy 305.trans am. And I recently put a 1992 camaro rs 305 Chevy block in it ..but I'm stuck on what flex plate I need to buy for the new motor to work correctly.

Thanks for replying back.but ya I don't have the vin..just know it was a 92 camaro rs 305 Chevyblock . Just have no clue what the flex plate I currently have is off of to get a new one. The 80 crank is a half inch wider then the 92 so the bolt pattern doesn't line up on an 80 flex plate. And the 92 is 12" wide /80 is 14" wide idk
