Does anyone know what kind of car chevy of course came stock with 3.90 7.5 rear gears?
My stockcar owner has a set already they came with a rearend he bought at a fleamarket. I want to put some in a friends stockcar that I built for him. Around here in NY everthing seems to be a secret no one will tell you anything!
Any help will be greatly appreciated!

To my knowledge, they don't make 3.90 gears for a 7.5" unless you spend a lot of money to have them custom made. If you want 3.90's, you'll have to switch to an 8.5" rear.

I was told that late 90's police car's (caprices) had 3.50's and some had 3.90's. Like I said we already have a set so someone is getting them from somewhere? The one's we have, have no markings on them!
