I had this in the 1992 Z28 after the cage was built. So, I modded the bracket slightly (rounded it for the small tube it was on and drilled the holes out a size or so). It has a slight mark on the lens and is in otherwise good condition.
$90 OBO plus freight
I also have a set of "odd" MSD rpm chips (6100, 6300, 6500, 6700, 6900) that have mostly been lightly used (and a few that are still new in the package).
$20 OBO plus freight
Or, $100 for all of it and $5 freight (and I'll cover the rest).
