harmonic balancer
Does the balancer on a 95 Camaro measure differently than a 97 Camaro? I have this low mount alternator bracket and the pulleys don't line up. The instructions say it needs a 92-95 corvette or camaro balancer. I assumed they just left off 96 and 97

I think I found the answer that obd 1 and II measure different. That would explain it, but feel free to confirm this for me 
. I did not plan $200 for a new balancer...maybe I can find another bracket

The hub on a 96-97 is shorter than previous years due to the addition of the crank reluctor for the crank sensor. If you have the short hub, you could just use a spacer (the thickness of a reluctor) to take up the difference.

The only thing that changed on those hub and pulleys were the different length of the hub but ive never heard of using a spacer on a hub to make up the difference that seems like it would be a weak point due to the hub and pulley not being right up next to one another.

Surprising that the shop suggested either/or on a Corvette vs. F-Body hub. I always thought the Corvette and the F-Body hubs have different lengths, since the Corvette belt spacing is different than the F-Body spacing.

I forgot to post yesterday, but I ordered a spacer and they also threw in a set of 5 different alternator spacers for the fan just incase I need to tweak things a bit. Hopefully this should do it.
Fred- Here is their description: "Will work with LT-1 engines using a 2 1/8" thick Corvette balancer and a G.M. CS130 alternator with the 6 & 10 o'clock mounting points, part # 7861. If using a Caprice, Impala or Buick engine it will require a crankshaft hub G.M. part # 12553250 used on 1992-1995 Corvette and Camaro - Firebird engines."
Adding the spacer should give me the corvette spacing so hopefully it will work, but I won't know for sure until I try it I guess.
