well i finally put my underdrive pulley on that i bought from nick boers. very nice product and decent gains from what i could tell. the only problem i had was installing the belt for the alternator, but finally figured it out. nick if you read this i need to know where those spacers go? the old pulley and new pulley were the same so i didnt put them behind it or use them at all. was i supposed to?

One of the belts is pretty tight, there was no better sized belt available.

The spacers were to go behind the pulley in the case that it touched the timing cover. It's happend on a few cars, so i've changed the design of the pulley for future batches, and had been supplying the spacers with all the parts i had on hand.
