Selling some major items you will need to convert your V-belt system to the newer 6 groove single serpentine belt.
The GM part #'s are
10129515 passenger side bracket (A/C and Smoke pump)
10118701 drivers side bracket (generator and Power steering)
14102108 tensioner pulley and assembly
The setup came from an 92 full size pickup with a SBC 350 but will fit all the 87' and up sbc's and 4.3's and may work on the earlier years too if you're block has the bosses for it. These will work with carburated or TBI engines. I don't know if they will work with TPI. I listed all the GM part numbers above for your reference. If you need I can send TIF engineering drawings from GM.
I'm located in Grand Blanc, Mi 48439
Selling both brackets for $25 obo plus shipping (Shipping is roughly $10-15 for both).
Thy're ready to go.
