I really don't understand the question. What is the problem? Gearbox cross member?

When I got the car the car was squared up and on a rotisserie. The cross member was out and one of the supports coming from the front of the car had been replaced. Before I put the crossmember back in I want to check the positioning from a front reference point to the crossmember.

I don't think you can install it wrong. There should be two holes on each side at the bottom of rails, they should have weld nuts inside, the other four holes match up with the top and are screwed in with the removable floor section. If that doesn't work measure center to center from the engine mounts to the gearbox mounts.

By the way, it would be easier to put the engine and gearbox in first, then attach the crossmember.

It is not the transmission crossmember that I am referring to. It is the welded in center section that goes from rocker to rocker and serves as the structural member that supports the floor sections and center floor section.

I don't know if you have this picture or not or if you have installed one of these front ends before so here goes. I would not trust a tape measure to accurately install that crossmember, if it's 1/16" too far forward you can't slide that C washer in, if it's too far. Back the splines in front will barely be in the arms. I would assemble the bottom suspension, find a1/16 washer that will fit through the hole in the crossmember and put it on the torsion bar first, that will give you enough play to remove the C washer for disassembly. Snug it all up and weld in position. You don't need to do the tension part right now. Another note, I hope they marked the torsion bars left and right, they need to go back where they came from!

I am about to undertake replacing center crossmember on my 67 minor also, I like the suggestion about putting the torsion bars in place before welding, any other advice about this job would be greatly appreciated

Just finished replacing the center crossmember on my minor, alignment was not a problem , dealing with the spot welds and weld seams, was where the rub was for me
