Yes, I replaced with an 8 3/4... pretty easy swap
Replaced the rear springs with the ESPO
www.springsnthings.com ones stock height. Had to get a different drive shaft whitepunkonnitro on the forum supplied that.. A universal joint that adapted the smaller driveshaft yolk to the larger yolk that was on the 8 3/4 (mine had a heavy duty one that is larger than normal). Had to locate some spring perches/shock mounts and new u-bolts for the larger diameter axle tubes on the 8 3/4 ebay or on they are listed sometimes on the forum classifieds.. I think I had to get a new brass vent tube/brake splitter for the new 8 3/4 too - ebay .. My 8 3/4 came complete with everything including brakes..
Took me a bout a 1 1/2 days by my self, including cleaning, brake bleeding / rebuild and time off for beaks, beverages and sleep.. lol
