Thanks guys. Yes, the Hotchkis bar has a proprietary bracket. Right now the plan is to source one locally, and barring that I know someone who knows someone who welds. If that fails on the drive up, well, guess I'll drink beer and watch the Pro while waiting for a new bar to show up.
God forbid I have to actually wrench on the car in Lincoln, y'all will discover how terrible of a mechanic I am.
