People with a LT1 Vortech supercharger

i know this is an odd request, but the harmonic balancer that came with the kit, how thick is the inside bracket where the 3 bolts go?

I think I know what you're getting at. Vortech sent me a 6.66" crank pulley instead of a balancer, so I machined mine flat on the front.

Machine the front flat, down to the countersinks for the 3 bolts. The machined thickness should be .340", per a drawing I had them fax me after raising hell for forgetting my balancer.
