I know this is a double post, but I wasn't sure if I should have posted it in the race area or here. So here goes.

I'm welding in the coil-over shock crossmember. Prior to this, the ladder bar suspension was triangulated, which came out perfect, and the lower shock brackets are welded onto the housing the same distance on each side from the axle flanges. My problem is the upper shock brackets on the newly welded in crossmember. I triangulated the ladder bar crossmember prior to welding, but didn't triangulate the shock crossmember as the directions did not call for it. All the instructions called for was making sure the shocks were perfectly straight up and down from front to rear and side to side. I made sure the shocks were fully extended used an angle gauge to make sure the shocks were perfectly straight up and down, but to make that happen, the drivers side shock upper brackets are 3/8" closer to the frame rail than the passenger side. Is this a big deal, or should I just get over it?

Make that crossmember as solid as possible and the same height on each side.

Your upper shock mounts will need to be much stronger than stock due to the load the springs will place on them.
