I received my SFI damper for my 292.This is how it stacks up. In the picture the V pulley on top of the crank trigger will be turned down and the center used to clamp the crank trigger and adapt the big bolt pattern to the blower pulley pattern. It was much cheaper ($109) and easier to buy the pulley and cut it down than make it from scratch. I need to make a spacer for the inside of the serpentine pulley to the crank trigger. BHJ also sent me an extra "slip fit" hub for mocking up free of charge. Thank you for your time.
