So, With an 8.8 housing, cut off 10 bolt axle tubes, I would just need the moser axles for a ford center section and fbody bolt pattern in addition to the carrier/dif etc.. Also, since the axle tubes are out of the 10 bolt, I'd be able to use LS1 brakes? Or is my reasoning wrong and i'm missing something?

The only way to keep ABS at this point is if you have a 4 channel rear end, the 4 channel cars have sensors at the end of each axel and since your keeping the 10 bolt tubes you'll be fine keeping abs and tcs. I have heard of someone trying to make an explorer rear end with a top mounted abs sensor work but I don't know how that went at all, but if you wanted to keep it with a 3 channel car you'd have to have the proper hole in the top of the housing for the sensor.

It could be done, but you are still going to have to rig up something for your torque arm or go with the extra bracket on your control arm like the guy in this thread is doing.
I think most guys go with the 8.8 because you can get parts for them cheap, as that's what all the mustang guys run.

I think if people looked outside of the "Normal" car envelope they would find that there are a lot of other cost effective options. For example, off road and circle track. I fail to understand how parts can still be so expensive for the F-Body's while other cars like the Mustang or G Body are more in line with realistic cost. Just take a look at a bare 9" housing and figure out why it would be so much more expensive to build a F-Body housing vs. a Mustang.

8.5" rear axle 8.8" rear axle
50-100.00 for assem. housing 50-150.00 for assem. housing

this is a mild break down of actual cost.Please dont get me wrong i would PREFER using an 8.5'' rear to keep me all GM but as you can see saving a few hundred bucks is what we are doing here. ABS can be added to either you just need the parts,axles can be ordered with rings etc..

For many years the 8.5 has been used,i prefer the 8.5 from 73-81 since they are beefier however the reason for not going the 8.5 route is the cost:
8.5" rear axle 8.8" rear axle
50-100.00 for assem. housing 50-150.00 for assem. housing

BTW to the guy that mentioned the 8.5, the 4wd blazers came with a 7.5 just like the f-bodies, unless you have a fluke vehicle, but to my knowledge they were all 7.5s

The 8.5 did come in some S10 4WD Blazers with a 4.3. Look for a 99 up disk brake 4.3 4wd blazer and they should have a 8.5/8.625 rear with disk brakes. They are 59 1/2" if I am not mistaken. I think the ZR2 option is 63" and has 30 Spline axles. Some of the ZR2's also have 3.73 gears. With a mini ladder bar set-up it might be worth a shot to check out.

'80 Z28 8.5'' rearend complete (already have, but value is around $350)
3.42:1 gears included (other ratios used are cheap/new are no more than 8.8)
Positraction (3 series included)
Stock axles (fairly strong & already Chevy pattern)
Same deal on arms and heim joints
I would use the LT1 brakes and caliper brackets (they literally bolt-on)
Possibly get c-clip eliminators
2" aluminum bolt on wheel spacers (already have, but value is around $100)
Looks like about $600 give or take (plus the same amount of labor/welding as any other rearend swap) if you had to go out and buy the rearend and the wheel spacers. The rears are fairly common. All this also assumes a donor 7.5" for the brackets and brakes.

I'd still like to find an 8.5" with a compatible ABS system and keep the 3 channel ABS functional though. Not sure if this would mean using a later model housing or if I could adapt things from the later one into the 80 rearend?
