I've searched around and found no help. I'm swapping to a D60 out of a 79 f250. I mainly just wanted to know what U-joint I have on my truck (89 1/2 ton burban) and what U-joint the D60 had on it. I've seen the yokes they sell for D60 to convert them to what you have but I dont know what I have Can anyone shed some light please? Thanks!
