Steering column clearance to headers

The first picture above of #3 tube gives you an idea of how it can't go together very far out of place frt to rear. Headers to torsion bars and steering box won't let you go far out of spec side to side.
It really only fits in a very precise spot when using stock style mounts because of the headers. If you have 1/8" clearance in spots you are doing very well.
I wasn't able to double check as much as you can having all your parts. The more parts you install the
better you can confirm you are where you need to be.
I do feel I got a bit lucky not having any heads or headers when building my K-member.
