His main bracket is $900, worth it if your belt doesn't slip at max boost.

I'm waiting for black friday to buy everything 
The one from indiana muscle has a spring tensioner and you can get a 12 rib bracket. You can't get this from procharger as far as I know.

Unless your guy building them, they should be the same brackets. you can call him though -
Re: My 86 Procharged 6.0 Iroc swap
That's the LSX bracket Procharger sells. Wont work for our cars. If you call Procharger, again, they would refer you to Justin at Indiana Muscle car. Plus IMC's bracket is 12 rib. Bob at Brute Speed is the man for Procharger stuff and I wouldn't hesitate to buy from him, however, that's not the bracket you need for a third gen.
