I recently purchased and installed an underdrive pulley from ebay for $25 + $15 shipping. I think it was a BombZ pulley but no brand markings.The product looked new and had good finish. 3 things wrong though: Powersteering section has 4 ribs instead of 3; Gatorback belts have no problem with that. Woodruff keyway was too narrow for my key. I handfiled that to perfect fit. Also, no timing marks. Had to line up with stock pulley then manually mark. Installed and runs great so far. Engine runs much smoother and better acceleration. I'll update if anything goes bad with this product.
