I installed this kit on a Dana 60 from a '76 Ford F-250. I think it is designed/intended for a Dodge spindle application because the tabs on the washers that slide into the spindle slot were slightly too big for my axle spindle slots. I had to file the tabs down maybe a couple thousandths of an inch or so, but it worked. I'd rate this kit a 4.5 / 5 stars for that inconvenience if I could, but the overall quality seems good. It would be great if they had more washer options to fit more applications correctly. The important thing is that the nut size and treads were correct. The nuts also work with the standard 6-pt axle socket that I had previously purchased before. I also suggest ordering the instructions if you haven't installed this kit before.
