I finally got time to crawl under my '88 today and here's what I found out: The spring code on my rear springs is NNL, not apparent on the chart though. Didn't check the fronts..i'll let you know. Also, I tried to find the code on my rear end but I had no luck. I thought it was supposed to be on the front of the driver's side axle tube. I did find what appeared to be "G29F7" on the bottom of the "pumpkin"..it's a Borg-Warner and it's definately a posi. It also has a sticker on the diff cover that says "Austrailia" and "4ET". I'm just curious as to what gearing I have. AND I found an aluminum drive shaft which I thought only came on 1LE cars. Is this odd or am I just a bit ignorant with this stuff? Any help would be appreciated....Thanks..

Ed,I will say that your rear> Is a 1987 2.77 posi B&W rear. With aluminium calipers W/12" rotors.ALA 1LE type. The aluminum driveshaft may have been installed by a previous owner.

It wouldn't suprise me if the rear had been changed. I bought this supposedly "one owner, 41K original mile car" off of some people outside of Boston (first mistake) about 5 years ago when I was a little more naive than I am now. I found out that I had been duped when the DMV wouldn't reflect the "original" milage on the title. Then I found a piece of tape on the steering column that said "83 Camaro", a ton of broken glass under the rear seats, and other oddities here and there. I can only stress to guys purchasing cars to check every last detail..and don't trust people for sh*t. At least they were nice enough to leave me with an alum. driveshaft...cool.

Ok, I finally got under the front..I have BZW springs, P/N 14029397, and my sway bar is DDH, P/N 14094339. Anyone know of a sway bar chart? I'm curious as to the size..but that mother is big! Also, I could NOT find a stamped rear end code on the passenger side tube.
