custom GM alt mount

That bracket looks great.

Just an fyi tho for a small block, you can use stock mounts and a 105amp CS130 alternator from a 1994 V6(3.4) camaro/firebird. Its actually scary how well it fits. I'm in the process of wiring up the last few wires before i can fire it up. You just have to swap for a v-belt pulley.
