I wouldnt put a piece of crap rear in a nice truck like your apache.
Find something from a newer truck, seriously, thats is too nice a truck to put in a rear like that. It probably wont last once you start having fun with it anyhow.If it is worth doing....do it right.

Gen three rearend

Seeing as I have had 9 gen three Camaro's I am familiar with both rears. I have had much better luck with the nine bolt rears as far as strength. The ten bolt can be made just as strong with axle tube welding, and girdles. I should warn you though that the 9 bolt only has a few available gear ratios and they sell for a pretty penny. I could almost buy a new posi unit for the price of a 9 bolt gear set. I will say that I ran a 406/th400/9 bolt combo on slicks and did not break it, BUT it was starting to get really sloppy after I hooked up a couple of wheels up launches. I agree with latech. If you can find a later model rear that was comparable in width; I would do that. :cool:

What about using the original diff? They're actually a pretty good unit.
That is what I was thinking also.
Why not try a ford 8.8 inch swap. Independant suspension, lots had disc,and they are strong. The one from the supercoupes 89-up were a little heavier. they had larger side gears and axle diameter and cv joints.
Just a thought.and they had disc brakes like you were after.

Some of the older town cars had a solid axle rear and had disc brakes.
I dont see the need for disc brakes on the back as the rear only does 40% of the braking - tops.Unless your going to haul some weight It wouldnt be worth the money.
I really would be looking for another chevy gear for it, JMO
