Check yours, you SHOULD be '7730 but sometimes there is different. The '7730 was used on TPI F-bodies along with a TON of 3.1 V6 cars (except W-bodies). Go to a wrecking yard, look for early 90s 3.1s and check the VIN for the 4th digit. As long as the 4th digit doesn't say "W", you will be okay.
Cavaliers are the most numerous and easiest to spot between 3.1s and 2.8s. 2.8s use MAF and won't work.
