Installing inner fender, 64 Barracuda

NOw I had thought about getting it really straight, then using the small sheet metal screws to get the thing into the best position possible, then welding it together, but jumping all around as to which hole to weld, that way, not throwing too much heat into one area at a time. Then removing the screws, tacking welding the holes shut, then doing the grind thing,

I've never tackled this kind of project, but this is MY restoration project and I want to do abso-freakin-lutely as much of it myself as I can possibly do.
