ok.. i havent been around for a bit.. im in iraq for my 2nd tour.. and im planing alot of upgrades for my 2g when i get back. i would look around the forum but the internet is uber slow here. i have been lookin at some 3.73 ring and pinion gears replacements but i have no idea what kind of rear end i have on the car. if any one could give me some info. something you might need to know. does a 8.5-8.6" 10 bolt sound right??

take a look at this.. is it right?

 

Don't know of a 8.6", but they made them in 8.5" and 8.2" back then. Hard to say which your's has. Best to waituntil you get home to actually order one.
On another subject...Thanks for your service tode5tool!

 

8.2's should have stopped in 70 for 2nd gens and picked up with the 8.5's in 71 IIRC. I think the 8.5's and 8.6's ring gears are interchangeable depending on the year as the pinion's width changes by like .001's of an inch. I would double check on that though and I think they're both 30 splined yokes.

I know you're in Iraq but there's also a stamped number on the front of the axle tube on the passenger side. You may have to take a wire brush to it to see it but it will give you the information of what came in the rear end. Now if it's been changed in that time then who knows. You can always jack the rear end up and turn the driveshaft and count the tire rotations to get your ratio.
