Well if the piece you made looks alright and you didnt warp the metal to bad, then weld it up solid and grind the welds flat.Then just put a thin coat of bondo over the weld seam.It really dont matter how bad your weld looks because they get ground down.As for the other cab corner im sure theres companys selling patch panels that are already shaped ready to weld in that probably arent to expensive.

LMC truck has all of the panels that you need. Get one, measure, cut out truck cab, place and MIG weld using small skip welds until the entire seam is welded. Their panels are good quality, I just replaced the left rear cab corner on my 95 SuperCab with one of theirs and you can not tell it was ever cut.
If you don't care about the looks so much, fab up some sheet metal and weld it in. Again, use a MIG or wire feed using small skip welds to keep from warping the panel and body. Grind flat. Then using VERY thin coats, skin it with bondo, letting dry and sanding between each coat. Prime and paint. Your set.
Good Luck

on my 59 both front corners were rotted so me and my dad fabed up pieces and oxyacetalene welded it in as we dont have a mig and then ground the welds down flat and it didnt turn out to bad for a 15 year old kid and a ranchhand in wyoming with limited metelworking and welding skills mig welding sure would have been a lot easer

LMC truck is at lmctruck.com, but i just looked and apparently they dont have a catalog out for 97's yet. You need patch panels on a 97 already?

Well i got 1 side welded on. havent done anything else to it tho. i think i may cutt it off because i have a new idea. i was thinking of getting great stuff the expanding foam and using that as a filler. it will quite it down and then i can just sand it smooth and then bondo over it. what do you guys think??? i was thinking of filling the whole cab with it or where ever i can to quite the ride.

Yea. Both sides at the rear bottom behind the door have a good bit of rust. It's not the door, actually it starts right after the door jamb. The jamb is ok, but it starts about an inch behind it. Maybe 6 inches high and 2 inches wide. When the weather changes I was going to start cutting, but I need something to put over the hole. The truck is white so it is easy enough to paint. My 96 has no problem at all.

I think your bondo will crack out in no time.The only way to fix it right in my opinion is to cut out rust, them replace with metal.And chances are if your seeing bubbles in your paint, its probably already rusting pinholes through the metal.

Everyone is missing something here. If you are not that good with the welder, than don't do it. One possible other method is to buy patch panels, trim them to fit and apply them with Speedgrip or Duramix. We often do 1/4 panels this way & you get a extremely strong bond with no panel warping.
And, its perfect for those that don't have great welding skillz !!!

All I need is a clean piece of sheet metal. Where mine is rusted it is rather flat and not real big, but it has to come out. Where do I get Speedgrip or Duramix? Are they like an epoxy? Thank you.

Yes, they are a 2 part epoxy type adhesive. Many OEM's use them for body side panels, such as vans to attach without getting warpage. Look for a local auto body paint supplier, they will carry a product that you can use. There is also one made by SEM that you may find. Also, you may want to look for a pair of flanging pliers from a tool catalog such as EASTWOOD, or go to Northern and buy an air powered flange tool to flange the edges where you cut your metal out so that the new metal fits in at the same height as the old & you need less body work to cover it.
