Need Zbar to frame rail bracket

My 68 Dart 340 SB was apparently converted to 4spd at some point, and not so well done! There was no bracket used on the frame rail end of the Zbar...just poked a hole throught the sheet metal :realcrazy:. Predictable result:

So, now I'm looking for the correct frame rail bracket for this end of the Zbar. Or, should I just used some heavy plate and fab one myself? Where can I find the correct bracket?
I assume that the location and alignment of the hole is pretty critical to clutch pedal operation. What is the best way to set it in the correct place? Should I cut away that old sheet metal and weld directly to the frame rail?
