On my '64 with the dealer-installed A/C, the installers removed the x-brace in the core suport and never re-installed it. The dealer-installed kit should have came with spacers to allow for the condensor clearance because the x-brace on the non A/C trucks is straight and not curved for clearance like the A/C-specific brace. That caused a multitude of issues, and it had stress cracks everywhere on the inner fenders and core support because of this. I got a original factory A/C core support out of a '65, and the x-brace is riveted at the bottom and bolted at the top. All factory, never molested. Having it unbolt at the top makes it possible to slide the condensor in place without having to remove the entire x-brace.
