So I don't really have a good answer for that question because I made my console brackets. My '74 was a bench seat, column shifted car to begin with so it never had factory brackets and I wasn't going to spend $100 on factory brackets that I knew I'd probably have to modify.
I located the console based entirely on where the shifter was, I just set it in place, got the shift handle opening the top plate in the right spot and made the brackets to fit the tunnel where it was at. The front mount is just a piece of flat stock I bent to match the tunnel and console, the rear is a ~1.5" wide section of 2x3 tubing I cut so I had a "C" shaped section of the correct height.
Overall I think the console is a few inches further back than the original factory location, so if you have factory brackets they wouldn't be in the factory location regardless. I didn't compare the bracket heights to factory so I can't really say if a factory set of brackets would work without modification. I would suspect that they would need some modification.
