I believe they used to call this wide set up FatBack. It was the only system I ever new to break spindles. They have huge offsets on the wheel dish creating leverage several times the leverage of a standard dish rim. If you have the chance to change to 8x20 or 10x20 rims, 24"may be to tall, with tractor tires running backwards you will be pleased. It was actualy an option on l2 and 3's. The tires will grip and roll instead of plowing 16" wide path. It was standard on R models, look on the internet, virtually every r50 has some kind of tractor tire on the back. You will be pleased, and used rims and tire set would be cheaper than one spindle. You should have 8 lug hubs and wheels, Good luck
