I've got the entire floorpan removed at this point except these two pieces on both sides (For reference, these pics are of the floorpan between the rear fram rails and the inner wheel well). Due to the distance from the frame rails and torque box, I can't get my drill in to drill out the spot welds. How have you removed these pieces?

Use a cut off wheel on the spot welds. I use that tool more on spot welds on metal I`m not going to reuse a lot as well as an air chisel when I`m not worried about damaging things.

Yep, cutoff wheel then grind what you can to get at the spot welds. Drill the minimum of spot welds as possible. The area at the torque box, leave about an 1/2" to spot weld to if you don't want to separate the floor pan from the rocker. Makes it easier to weld too. If you wanted to, you could also stitch weld that across the torque box to save alot of time and preserve the seam there.

Im guessing your putting in a complete repoduction one peice floor pan. The new floors allready have the torque boxes spot welded to them, so removing the troque box to get access to those spot welds is always an option.

I will be using the complete repro floor pan.

Thank you guys for the help! I will try these suggestions.
