Looks like you're having fun! While you have it apart like that have you considered making any other repairs to the body.
I'd recommend running a continuous bead when you weld that pan in.

First i need to weld that dang hole in the roof up then i need to weld the floor pan back in aswell the radiator mount is cut so the radiator is sitting kind of at an angle im thinking i should just pull that along with the fender aprons attatched or can you separate the radiator suppor from the fender aprons?

I dont recomend a continuous bead on floor pans. Once its all tacked in there, then you can do about 1"-2" long beads, but if you just start in one corner and weld around it, its going to move around from the heat. Just did the full pan in the 71 last night, what a joy that is. Anytime I work with sheetmetal even underhood or where nobody will see it, I use the stitch method rather than a continuous bead, heat does strange things to some sheet and you dont need to be filling a 1/4" gap at one end, and have the rest of the part not line up either. I do have the time and patience to do it that way though.. so to each his own..


As for the radiator support, if you are carefull and dont have a ton of rust under the battery tray, you can pull the radiator support off and replace it, I tend to cut things apart rather than drill the spot welds, at least when I am not worried about keeping the piece I am removing. If you need to keep them like the cowl, then its a good idea to drill them out. otherwise its sawzall, cutoff wheel, air chisel, and other implements of destruction that get the nod.. Just dont tear up the good stuff you want to keep.

The roof, you will most definitely need to controll the heat, otherwise everyone will ask what that bulge in the roof is from.. Small tack welds only there... with plenty of cooling time between them since its a relatively small area.

Maybe my understanding of a continuous bead is wrong. I meant just a bead all the way around instead of welding it in a few areas and then using seam sealer to keep out the elements. You are right about how to go about putting that weld down though.
