I have a full serp belt bracket setup with a/c compressor, P/S and Alt., including a reverse rotation waterpump and the reverse rotation fan and clutch if needed
one thing though, IIRC the crank pulley is bent, but its a standard one, all SBC and 4.3 serp setups used the same one
actually I have 3 different ones, a TBI truck setup with everything, a TPI F-body setup minus the Alternator and a Vortec truck setup that has a siezed A/C compressor
