We have used the Colorado/Canyon rear both drum and disc. Can't remember if the 2wd or 4wd one is the perfect width (61"). Has 6 lug pattern on 5.5 bolt circle. The Isusu Trooper is also 6 lug and just a tad narrow which can be cured with wheel offset or spacers. It has a Dana 44 so any gear ratio or locking/open is available at a good price. If you want one that is a straight bolt in where nothing has to be cut and re-positioned with no welding involved---it doesn't exist or it hasn't since 1949 when I first started.
