FMXhellraiser......How much over lap on th floorpans? like a 1/4 or 1/2 inch? What type of sealer should I use once the weld is done and grinded?

Merlin I do have a grinder, so I will give that a shot as well.

Flanger tool = locking piliers, I have alot of those

I dont think I want to dipp this camaro but I would like to do it as best as possible. My next project is the 57 chevy you can see in my header. I hot rodded as a kidd and I am now just getting back into it and have found I have forgotten alot of stuff.

It looks like I am going to have to take out the seat mount and weld it back to the new floorboard as well as the gas tank mounts.

Thanks everyone for the advice!!!!!!!!!!!
