2. What is the width of the rear end from backing plate to backing plate? not 100% sure, but I can measure the spare I have in my garage tomorrow
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?
Buying a differential, gears, and all the bearings which will cost you about
$700 in parts plus you need to have the know how to do it. If you have never
done it, I recommend having someone that knows what they are doing build it.
4. Do I need to look for a certain part # or #'s that are the strongest rear? Nope, all the same
5. Any rear ends that I should avoid? Yes, the Olds 12 bolt. It has a 12 bolt cover and a 10 bolt differential, not a true 12 bolt
6. How much is a reasonable price for a rear end used/new? With posi/without posi? Depends on where you live, I've been seeing rears going anywhere from $500 and up, if it's a posi, double it
7. Are there any reliable vendors in San Jose, CA that I should frequent?
ie. GM Sports?
As far as what kind of parts? OPG is in Long Beach, True Connections is near
Moreno Valley
8. Does the driveshaft length change between a 10 bolt and a 12 bolt? Yes, the U Joints are also different
