emptnest

The car is 1993 Corvette with stock LT1 engine. I need to replace the harmonic balancer and hub (to which it mates). I am trying to acquire the necessary replacement parts before removing the original ones from the car.

I already have a new Dorman (594-107) harmonic balancer (aka: Crank pulley). It appears to be a true replica of the stock GM #10128489.

But, I am having trouble finding the hub, GM # 12553250.

All usual parts suppliers show the hub as discontinued.

I tried a supposedly compatible replacement hub from Jegs (#51607), but it would not bolt up to the Dorman balancer.

Does anyone have experience to confirm whether the Dorman balancer is a true compatible replacement for stock?

Making the assumption that the Dorman balancer is correct, I still need a stock hub (GM 12553250).

Any help will be appreciated.

as of two years ago it was still available from your local GM dealer

I saw this thread the other day and just checked my parents garage where I have lots of old stuff. Brand new LT1 hub was going to use it on my first 93 build like 15-16 years ago but didn't. Surprised I still have it !
