Just picked up a '72 (April casting date and 112 Julian stamp) 'KDC' code rear end (2.73, non-posi). It's complete from drum to drum, and appears to have never been apart. Tubes look like they will clean up nice, with only minor pitting. Didn't pull the cover or axles yet.

What's a fair market price for something like this? I don't think I stole it, but I think I got a fair deal. Curious what you guys think it's worth?

I'd guess $400-$500. I got a great deal on a similar 71 rear for
$300 a few years ago, but I had to drive 200 miles to pick it up.

Lately the way prices are in this area, I'd say in the $500-$700 range. It's getting harder and harder to find cheap deals anymore

As mentioned above, I think somewhere between $500-700 is realistic, where in that range it falls will depend on where you live. Some areas of the country may go a little higher or lower.

Last complete one I saw for sale was $400 3.31 open that had pitted gears and a guy from phoenix drove to tucson for it and was happy for just the housing. Last one I bought was the same as yours 2.73 open I pulled out of a 71 el camino. Drove to Phoenix and paid $400 for it. Im used to fi ding them for $100-$250 but those days seems to be long gone.

Thanks for the comments. I paid $500, so I guess I paid a fair price. Like I said, I didn't think I stole it, but didn't really think I was overpaying either. I still remember when these were more like $250-300, but I guess there are not too many untouched original 12-bolts left.

I remember when they were $65 at the local pick & pull.

The one in my wagon was a 2.73 open, housing was clean no rust, no pitting. When cleaned and painted it looked new. Paid $250 and drove 300 miles round trip to get it. Then spent another $1100 having it rebuilt with new gears, posi, axles and bearings. This was about 3 years ago.

I think you did fine if the axles are usable. 12 bolts in good non-pitted condition are definitely getting tougher to come by.

Last year I bought a bare housing for $200, with nothing but the caps. I let that go when I sold my blue 70 chevelle. I still have a 2:73 non posi that I picked up for $150 about 15 years ago. I saw it in the local want ad, all it said was GM coil spring rear. I called and he said it was from a 71 chevelle. I told him I'd definitely buy it and drove 70 mIles to get it.
Right now on local craigslist, there are about 5 of them. The cheapest is supposed from a 70 chevelle (although the guy won't gI've the axle codes because he doesn't want to scrape the paint) he wants $700, and it's a bare housing. Next cheapest is a 3:31 from a 70 chevelle for $1000. It doesn't say if it's posi or not, but I'm assuming not, because it's been on there for months. The others are all $1500-$2000 range.

There is a '69 Chevelle hulk for sale on craigslist in Arlington Washington with a 12-bolt rear, disc brakes, doors and tinted glass. It has no front end, engine or transmission. It looks pretty rough in the photos. Not knowing the condition of the doors, glass, brake components or other parts on this car, one could only speculate as to their respective values in such a package. Same with the value 12-bolt rear, which I would place in the neighborhood of $600 as part of this package. I emailed the seller some months back and he said he would help load the (non-rolling) hulk onto a trailer. I did not attempt to negotiate with him, as I was really only interested in buying a very nice tinted passenger door glass.

I would agree at $500.00 your in the park. Remember: this rear is for a specific application, for 1972: KD 2.73:1 ~ 12-bolt (L48/350-4). So it may have a higher value for a targeted restore or period application. Provided the guts are still good, you did fine. 12-bolt housings alone are bringing as much as complete 12-bolt Posi's used to.

Such is the case.

Ive got a KK code 4.10 posi in the shed. Guy has a $1200 offer on it whenever (if) I ever decide to sell. I thought that was crazy money but I cant go out and buy another 12 bolt around here to replace it. So it sits.

Found a pile of Chevelle parts a month ago 250 miles away. Buddy of mine and I paid $250 each for two 12 bolts from the collection. His actually turned out to be from a Pontiac Grand Prix 2.73 open and mine was 69 Elcamino 3.31 open. Axles were shot and no drums. Thought this was a fair deal.

About 5-7yrs ago (time goes by to fast any more) I pulled a non-posi 2.73 12bolt out of a 71 Elky that was 30min away from the crusher! Gave $75 for the complete rear and my son and I flogged to get it out before going into the crusher.
FINALLY, last month I pulled it apart and discovered the R&P were too rusty and pitted to use. I got a perfect 2.73 R&P from a member right here (only had to pay shipping). Several years ago, my son came across a 2-series 12bolt posi unit at a swap meet for $25. I bought a pair of new axles from Rock Auto which came with new bearings and seals (about $300 as I remember). I bought new rebuild kit from Rock Auto (about $124 as I remember). The clutches looked good, so I kept them). Cleaned, blasted and THOROUGHLY flushed the housing with gasoline (yes I did it outside), painted the entire assembly with satin black Rustoleum, put it all together and got a text book pattern the first time!!!! It's now ready to put into the 70. I have less than $600 in an essentially new 2.73 12bolt posi rear-------COMPLETE, ready to go.





My point is that REBUILDABLE 12bolt cores are becoming scarce. So if a complete 12bolt rear is available (regardless of the condition of the guts) for a decent price ($200-500) it's probably worth buying. Gears, axles, posi units and all the misc parts are available to put one in new condition.

And last but not least---------------THANK YOU Philip!

I just picked up an A body BOP 8.5" 10 bolt, 3.08 open from a low mileage Buick wagon. Not sure what to do with it yet. If I hadn't already had the 12 bolt it would have gone in my wagon.

I built one of those for my friends '71 Cutlass. If you don't care about having the 12-bolt "look", the 71-72 Buick / Olds rears are probably a better bet. More affordable, just as strong (with 30-spline axle upgrade as we did to my friends car), and factory bolt-in axles.

In my case, the 12-bolt I picked up is going into semi-restored car where appearance matters more than strength (Dad's convertible he's owned for years), so the 8.5" wasn't really an option.
