I will give you my Underdrive Pulley, the Belt and the bolts.

In return I need your bolts, and a GOOD Stock belt. (No Value Craft or 70k Belt, pref a good Gaterback Belt).

I can help you with the swap if you really need it but I want to take it off, the Loss on my AC while at idle is to much when I have my son out in it.

Just let me know.

What pulley do you have? If its an underdrive that replaces the stock unit I may be interested. Now Im running a piggyback BBK pulley/ with the stocker..
I have orig belt and pulley low miles. (car only has 33k)

Its the piggyback hints the longer bolts. If you have an all in one you have a really nice one.

cross, if you just buy an overdrive alt pulley that will counteract the effects

For the Ac compressor? That would proly be hard to find a clutch for that Unless I am thinking wrong

Heres my problem with two piece UDP's.

The idea I do believe in, even though its been shown it may be a very small gain however this style setup makes no sense.
Whatever gain you might get using this one your adding unsprung weight... you just negated all the positive effects by using it.

Now a one pieces thats the same weight or ideally less is the correct answer.

I will get a Alt UDP but for now I would pref a full replacement UDP instead of this add on one.
