However, the surfaces you are bolting the crossmember to are not exactly the same. The various trucks I've measured have all been slightly different.
This IFS crossmember is bolted through the sides to the frame AND bolted through the bottom of the crossmember to the bottom of the frame.
The challenges are in the shape of the bottom of the frame where the crossmember needs to match up and be bolted on. The lower edge of the frame has a complex shape that on a 1-ton is not nearly close to flat. I don't know the exact shape of the smaller trucks, but would encourage anyone thinking about this swap to check it with a straight-edge before assuming this is a simple bolt-on swap. Also be aware most of the surface that needs to match at the bottom is ahead of the axle centerline.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
