The cross member is slightly different but not really any thicker. I'll measure though for curiosity sake.RSR wrote:I have looked at doing the same 4x converstion on an 83. I was told that I should replace the entire cross member because the one on the 4x4 is thicker than the 2x4. The shorter beams from the 3/4 ton front would cause the crossmember to flex and crack on the 2x4 cross member. Just wondering if you are going to keep the coils or swap in the leaves?
I plan on building my own pivots for the factory cross member then building a radius arm setup so I can retain the factory style coil buckets and coils. I'm not a fan of the leaves but they are tolerable with a good shock and shackle reversal.
