Need help on Corvette accessory drive! I am finishing up right now on a car that uses a Corvette accessory drive, but I have run into a road block. The drive belt idler mounts to the bottom of the alt/PS bracket, but the idler pulley I have has a inner bearing bore of 17mm, but the attaching bolt is only 10mm. I take it I am supposed to have a bushing/spacer that goes inside the idler bore, but I do not have one. Does anyone have the part # for this spacer? I have looked at several parts number listings for the Corvette drive and have seen nothing listed.

It's like a piece of a large roll pin pressed in the bearing to form the spacer for the small bolt. When you buy the pulley it comes complete with everything shown.
You could probably make a piece for it, but I don't think the part you need is available separately.

Thanks guys,
The idler I am using came off of a G8 and it has a shoulder on the bracket itself instead of a bushing. I just went of to a buddy's house and borrowed his lathe and made one today.
