Here's the Pioneer keyed hub for 94-95 Impalas: http://www.jegs.com/i/JEGS/555/51608/10002/-1
It might be too long for a '96 unless you delete the crank position reluctor.

Here's the Performance Products keyed hub AND balancer which will fit any
LT1 by using the supplied spacers. I've used these before on 2 of my cars.

thanks Nab,
thats the balancer i got, it came with a key but it doesnt fit too wide i was thinking of just grinding it down some with a dremel

anyone got pics of how the key sits in the crank

also do i put the key in the crank and slide the balancer on or vice versa

thanks for any help

 

The key that they supply doesnt fit, you need to get one from an autoparts store, machine shop, or hardware store.

You might need the stock one for a 96. Its a different part number due to the crank reluctor. I just got one from the dealer. The part# is 12550096. It has a step on it for the reluctor. I had to add one to my 383 because it was built from a 94 engine. Hope this helps!!
