Hi All,
I haven't had a chevy in over 10 years. I will be in need of a 12 bolt posi unit for my 69 chevelle. With that in mind, a few questions need to be answered.
1. what years of Chevy's can I use for the rear without modification?
2. What is the width of the rear end from backing plate to backing plate?
3. What does changing a non-posi or wronged geared posi to a right geared posi. I.e. I find a 12 bolt with a non posi, 3.08. I want to change it to a 3.55 posi. What is involved?
4. Do I need to look for a certain part # or #'s that are the strongest rear?
5. Any rear ends that I should avoid?
6. How much is a reasonable price for a rear end used/new? With posi/without posi?
7. Are there any reliable vendors in San Jose, CA that I should frequent? ie. GM Sports?
8. Does the driveshaft length change between a 10 bolt and a 12 bolt?
thanks Thomas
