1984 Buick Park Ave rear-end question
Hi, I was looking at replacing my rear-end gears for my '84 Park Ave. It is a 10 bolt pattern, but I'm not sure what series it is or whether it is an 8.5 or 7.5 (and I'm not sure how to tell). Would you know what it would be or how I can find out?
Thanks for your time,
Greg Hesterman
