With all this discussion of "making holes in the metal"...Are we ADDING the console as an option? Are we relocating screw holes because the full floorpan was replaced? Are we simply trying to find the holes already there that are covered with new carpeting and underlayment?
Personally, when I reinstall my original console back into my car, I intend to reuse the original holes that Ford made. I plan on dollying the original holes in the floorpan down a bit so the new screws will not strip. Second, once the carpeting is layed out and all adjustments and trimming is finished to it, (at this point, not planning to remove the carpeting again) I plan to install the console next (temporarily, without any radio at all) and align it to all of the original dash holes and mounting brackets. And then, I'm going under the car with an awl and from below, locate each of the holes in the console.( w/no driveshaft or transmission in the bare body) As I push a hole in through the underlayment and carpeting, I will remove the awl and insert a nail to mark each hole (sticking through the console holes) Once all 4 holes are made, I will remove the console and burn the holes permanently into the carpeting with a soldering gun.
I have before inadvertently on other cars, made a second set of holes in the floorpan because I was unable to locate the original holes. The result was oblonged, stripped holes. Do not wish to repeat that.
