If'n you want to do it right, I recommend you keep an eye out in the junkyards for a Montero Sport with leaf springs, disc brake, and an air locker in it factory. With this, it will BOLT onto the truck with no problems. You will go from an 8" to a 9" rearend. Youbwill have disc brakes instead of drums, much better with the bigger tires, and the ability to lock and unlock the rear at the push of a button. The parking brake cables bolt up, you just need to criss cross them. The biggest issue is driveshaft/u-joint. It is bigger on the Sport rear axle. So two ways two handle that. 1. There is enough space on the Sport flange to drill it and bolt up your smaller stock rear u-joint or 2. Get the larger Sport u-joint assy put onto the stock driveshaft. And while you are getting the rear axle out of the Sport, grab the front brakes; rotors, calipers, brake hoses, backing plates. With a little modification to the backing plates, you will upgrade to a lot bigger front discs.
