Need to Re-locate Factory Parking Brake Cable Guide/Bracket

Looks like 4 or 5 spot welds. Drill them out from the top (or use a spot weld cutter), then weld them back up. Piece of cake!

Then just drill a few 5/16"-ish holes in the floor pan where you want to relocate it to. Maybe use a jack and a block of wood (or a screw, tack weld, etc.) to position the bracket and weld it in from the top through the holes using rosette welds.

That's how I'd tackle it.
