I have a complete 10 bolt 8.2 rear end out of a 1968 firebird. It is a 3.55 posi, drum-to-drum with multi-leaf spring mounts. I have had the rear since the mid 90's and it has been in storage since 1995.
I am wondering what the street value of this is, I am trying to correct my hoarding ways and get rid of a few things.
Does it have a large raised capital "N" embossed on the top of the center section right behind the pinion yoke?

To clarify - if you have a 4 pinion nodular iron version of that 3.55 Safety Track rear end, it could mean a difference in value of about $1,000

Hi thanks for your response. I looked over the rear center section and there was no N near the pinion but there was a N raised and cast to the left upper iron webbing on the back of the unit near the diff cover - about the ten o'clock position. Near the N is a D and in the same spot on the other side is a 2 cast into the housing. I took some photos and will attach tomorrow.
Nah, the "N" I am referring to is huge - probably about 3 inches high.
So you have a "regular" 2-pinion 3.55 posi rear for a '68.
You can perform your own search here on "posi" and go back a few years. The "as is" price for you axle with its more desirable gear ratio seems to hover between $500 - $600.

Check axle code stamped on the driver's side axle tube near the brakeline retainer, will be ZN if it's a 4 pinion axle. You may have to clean off the tube with a razor blade to find the code. I don't think any 3.55 axles were 2 pinion. 3.55 was the first of the performance axle ratios offered for all the Pontiac performance cars.
