Hey, put me second in line -- I'd be real interested in a stock posi for a 69 GS.

I have a stock posi and 3.90 gears no housing

sorry for the delay, computer was down for a couple days.needed new video card. i was under my GS yesterday and couldn't find any #'s. i'am looking on the right side of the rear-end and towards the front of the car. took a wire brush under with me and still could not bring out any #'s. any suggestions?

 

The numbers are usually facing down on the right side of the car between the housing and the spring holder.

Look for 2 letters.

Go here and scroll down to the rear axle charts to find out what you have.

Good Luck :laugh:

thanks kitty, i was looking on the right front of housing. i'll look tomorrow on the bottom.

 

Posi #'s

Took A Wire Brush To The Bottom, Rt Side And Still No Numbers.

 

i don't know much, i'm new on the block. but i have a posi axle out of a 68-70 elcamino, somewere around that year, i don't remember is it useful to anyone.

 

posi for the el camino

I would be interested in that posi if it is an 8.2 chevy c-clip typ posi. Let me know. Jim

mitschke454@earthlink.net Thanks :3gears:

 

Steve,
Your best solution is to get the 71 Skylark 8.5" rear from the Tampa yard and then get a corporate 8.5" posi unit. Much cheaper and much easier.
You can find the 8.5" posi units in many GM cars/trucks/vans from 71-89.

 

12 Bolt Posi

Will a 12 bolt out of a 65 Riviera work? I don't know the interchange on these.

 

Only A-bodies interchange:

El Camino, GMC Sprint, 70-2 Monte Carlo, 69-72 Grand Prix,
Skylark, Chevelle, Lemans, Cutlass

 

skylark rears

Not so easy to find any kind of old car rears around here. Jim

 

Here is a listing for the corporate 8.5" rear posi unit on Ebay, buy it now for $160 is a fair price:
