So I have been working with DIY4X to get a spring perch for my front 78 dana 60. They sell a kit that is just one perch that is just made for this application. I can't figure out why mine is weird, so I need some help. If you have a front 78-79 dana 60 from a ford could you measure your cast in perch height for me. Mine seems to be shorter than most. I mean it is closer to the tube than the ones DIY4X has seen. Mine is about 1/2 of an inch off the tube to the top of the perch. thanks
