You do have an alternator pulley correct?
"FRIENDS DON'T LET FRIENDS DRIVE STOCK"
Why underdrive a LSJ? That would cause less boost. Unless of course its the same diameter...
I am selling alternator pulleys in the Group purchase right now.

I was wondering when this was gonna pop up.
Saw post all over ebay for these.
I'll try to keep my nose out of the specifics between the two.
As long as you guys keep offering (and shipping out) good psroducts.
Good luck with these.

Our's don't have the flattened sides on the mounting nose.
