cheapest way to do it is to find a posi unit out of another gbody 7.5 like a ss or an s10 or blazer. i found mine out of a blazer think it was an 86 got it and the pick a part for like 80 bucks...

I like the blazer idea, thnx
Any ideas for my "Headlight" topic?

do you have a test light since you switched out the fuses and stuff use the test light to see if your getting power to the lights.. if you dont have one can get one at auto zone for like five bucks....
