Cargo floor question!

[Stokester]

I'm in the process of installing a new rear floor in my 72 blazer. I have old floor out and ready to install new floor. My question is there are 2 holes on each side of the front of floor. I believe they are for bolting the rocker box reinforcement plate. Do I need to weld some nuts on the floor before I install? The old floor did not have any bolts in those holes but PO had done some work already!!!!!!!!! Any advise would be great! It's a gmcpauls floor if that makes a difference! Thx again. Mike
