Part 2

More........

I will do a follow up on measurements etc. It will take me a day or two. One problem I see is if your frame rails are different from production flaws it could end up wrong. Also I used a B Body Housing so my measurements would be based on them. As you start to put it together it makes more sense as an as Built Project, that is how I did mine anyway. It took me about 20-25 Hrs total to mock the whole thing up.

The pieces for the Link Boxes are as follows.

The finished product is 3 1/16 inside box measurements by about 12" long to catch a weld across the existing frame on the radius point.

4 pcs 5" x16 Fine tuned to fit
3 pcs 3" x16 Fine tuned to fit

I followed the frame rail by just clamping the first piece in the cut opening of the rail and using a scratch all to mark it. As you can see in the picture I held it down some and radius'd the edges to cover the bushing completely with the Plate. Most guys dont do that but I wanted the whole bushing to ride on material and not air. I used the hole in the existing frame rail to set the first link mounting hole and split the measurements I think 1 3/8's apart or whatever makes them the same distance apart, and I built them IN PLACE, not on a bench.
