Finally got an old pickup truck!

spindles should be same. what usually makes difference is gvw. i think outer bearings are same on some 150/250 and inners and seals are different. i have a chart in my files some place that will tell. i.e. i have a 87 150 2wd and a 93 250 2wd that will interchange due to gvw being same. will look for chart after steak supper.
