Dana 60 too narrow
1st pic obvious, inside of frame rail.
Second pic is a spacer I made from a template withe the floor contour at the top.
3rd pic is spacer in up against the floor board and only up to a point I can get a solid weld. I should say this is a final template for my thicker spacer plates
4th picture is the spacer with the us cartool spring relocation
5th is my little helper Tabitha.
6th my 470
