Hey guys I got a flywheel for a 5-speed but need to know what year it is :#3856579 the other number on it is GM2NF alright thanks

 

if it has a hole for a dowel pin it's 87 and later for one piece rear seals, no dowll pin hole and it's for two piece seals.

 

my flywheel has a dowel pin hole and my motor is a 2 piece rear main,

 

Thanks ede, it's for my buddy he's doing a T-5 swap to his monte, but got the Tranny and flywheel from a thirdgen. We know that the T-5 is from a 84 (part#)but don't know about the flywheel cause we know think the Camaro was a 91. We think that, the tranny was replace. Were just trying to make sure everything will balance out. Cause his motor is a one piece rear. Thanks again.

 

I'll second that.

Eric
