try ebay. they are all the same, n/a s/c park ave, montie, regal.
look up your icm on a parts store site, you'll have one part # to go off.
I tried that on one and i got a few different part numbers that they all said would fit and that didn't seem right. But some of the problem is they don't have an option for the supercharged motor.
