Some more measuring, planning, and fabbing. I finally did the math and figured out the spring and shackle hanger spacing. Got most of the hangers installed, minus the two in the front. For the Old Man Emu YJ springs I’m placing the hangers 44” on center. This should (theoretically) place the shackles near the center of their total arc when the Jeep is sitting level.
I’ve also decided to push the front axle forward one inch.
I cut and removed the original crossmembers from the original frame to use as templates for the new ones.
Here is the large crossmember in the works. I left plenty of slack on both sides to make final fitment easy. Since the tub sits directly on this crossmember I think it’s a good idea to wait until the tub is assembled and mocked into the frame to make the final bends and weld this member in place. I wish I could duplicate the smooth bends of the original, but at least mine will be stronger.
