Description:
This article was written by Mike Chaney who is a contributor to the F-body Listserv. He has done an excellent dissection of an Optispark distributor which appeared on 1992 - 1996 LT1 Corvettes. Below, he describes the replacement of an Optispark distributor on his 1995 Pontiac Trans Am. Keep in mind that the replacement *is* conducted on a TA and not a Corvette so there may be differences.
Excerpt:
"The photos on this page are of a 95 Optispark. The unit is held together with inverse (male) Torx screws. The easiest way to remove them is to get an old Torx screw out of something and hold the screw with vice grips. You can then fit the screw over the head and turn it. All screws have been removed in these photos to make access easier. This page is for your information only. What you do with the information here is up to you. I figured a lot of people would benefit from seeing one of these things opened up."
