im going to order a new keyed hub for my 93. but thunder sells 2 for the LT1. the longer is for the 93 - 95's. the shorter is for 96 + 97's. but if ive upgraded to the new vented opti witha newer timing cover from jason cromer. im not sure which hub to get. any ideas.

also the stock hub worked fine and didnt leak, but since they offer both sizes i want sure because of the new timing cover.

any help would be great.

 

the shorter hub is for the OBD2 cars with the crank sensor reluctor

so you need the 93-95 one

 

Dave89IROC is correct. The reluctor acts as a spacer as it is slide over the crank snout inside the timing cover. Therefore you need the shorter 96 - 97 hub.

 

thanks Dave i wasnt sure if that was the reason or if it was the difference in the timing covers. good to know though

thanks again
