actually the best and easiest so far has been the S-10 spindles. The arms in relation to the spindle and distance to the hub is the same on the S-10 and Luv. When running Toyota stuff the upper arms have to be 1.5" shorter and it makes for lots of camber change on a bagged truck.
The Mustang II stuff is about the same as the S-10 and the good thing there is the ability to run the chrysler style screw in balljoints. Either way my current plan is to always have one of each version in stock for coilovers and for bags.
