it really depends on what you will be using it for. On older housings like mine pre '98 you can use standard Dana stuff on them as far as the R&P go. So your choices there are unlimited. Since I do not know what you will be using it on, it does have 6X5.5 bolt pattern, like most chevys and toyotas and some other import trucks. As far as the shafts go if they break they are like $300 or more each from dealer, so custom shafts are in order. It has disc brakes if it came from V6 Rodeo. They are 58" wide +/-. On 1998 Rodeos (new body style)they are even wider 60" plus but Isuzu went funky on those rear ends, nice thing about later rear ends is that they are set up for 4link as the 97 and prior is set up with SUA. Gear ratios are 4.30 for manuals and 4.10 for autos. I have used mine pretty hard and hasn't given me a much trouble, this weekend I am planning to weld the rear up as it is dedicated trail truck now. Hope this gives you some info. There is a bunch of info on Isuzu stuff on Pirate Isuzu board, also visit 4x4wire.com Isuzu board.
