Two have tryed it that come to mind and both trucks are running ford 9".
Watched a 750 rwhp, 3900 lb TA make 50 passes at a time on a stock 7.5 rear. The 8.5 is much stronger than people realize. Especially with an auto and turbo the stress on it is'nt that bad.

swap in a 14B rear... or go D60 or 9"..... 10 bolts can be made strong, but you cant beat any one of those rears even in bone stock form for a swap....

Will a rear end from one of those trucks be a direct bolt it?

you have to move the spring perches and do a couple other small things but other than those minor mods, yes, you bolt it up.... I believe this swap takes the bastardized U-joint as well.... I'd keep the drum brakes too, unless you just wanted disks...
