If I am interpreting the photos correctly those have a gusset that is designed to tie into the front leaf spring perch (looking at the third picture where the pair are laying on the ground, at the close end of the pair, the one gusset is close to the "AJ's Offroad logo).
Is that interpretation correct? Or does that gusset tie in someplace else?
If it ties in someplace else then these would probably work, but if it needs to tie in at the front leaf spring perch I would need to cut them up and redo that mount. I have a welded in brace on my front perches. It won't play nicely with that gusset.
I need to find the hardware and take some detailed pictures of what I have. I bought them 3 years ago and the design might have changed. When I bought them I did not have any plating or frame stiffeners so the distance to the pinch seam mount would be wrong for someone with them.Another issue you might have is with the part that's meant to bolt to the pinch seam. If you've plated your frame rails, then the space between the frame rail and the seam will be shorter by the thickness of the plating. Of course, either one of those issues -- the gusset and possible need to account for plating -- can be overcome with some minor modifications.
