? for 4wd experts

I am putting together a 72 1/2 ton 4wd. Getting ready to work on the front end. There were 2 designs of the spindles. Mine have the 1st design, I am wanting to replace them. Cannot locate any first design spindles. I have located some NOS 2nd design spindles. The question is can I switch to the 2nd design as long as I use the bearings and all to match or are the actual axles different also. As near as I can tell the only difference is the outer diameter of the spindle. Just thought Someone out there might know for sure. Thanks, Bill

Hey Bill, from what I remember the difference between the dana and the spicer spindles is the bearing surface. if you try to cross match the bearings it will tear them up. My neighbor went through the same thing on his old Blazer. Either spindle will work but keep the bearing the same as the spindle.

You just need to use the hubs and bearings that go with the spindles that you use. The axle shafts are interchangeable. The '73 and up axle shafts do use the bigger 297x (5-760x) U-joints, but the lengths and spline counts are the same.
