Rust repair

[slotard]

My '73 C20 has plenty of surface rust, including lots of missing paint, but no visible holes. Well, I was swapping my seat yesterday, pulled up on the carpet and it turns out I have some holes. I hadn't even thought to look before, it's always been a California truck as far as I can tell and with no holes on the outside I didn't think to look that close.



Looking from below I only see holes along the line the ones there are on, and a few on the other side.

Any suggestions on where to buy patches? I'm an ok welder but haven't done any bodywork. Where is a good bodywork guide? I certainly don't need perfection but holes are a different story.

I have used Key Parts which is a decent replacement. If you use Top Banana understand you will receive nothing more than a payment confirmation and the parts arrive 7-14 days later. Nsanehotrodz sells the same brand Tri-plus / Key and is a board member. There are other board members/vendors but I can't remember all their names.

I'm assuming that rust is probably inside the outer rocker and kick panel as well but hasn't come through the exterior metal yet. I had a small hole in my front fender, turned out it was also in the rocker/kick panel/ floor support where those pieces come together.

Since I have no holes elsewhere it's possible that there is (or was) a windshield leak resulting in puddles there, leading to the rust.

If I have to do rockers I'll probably do rectangular tube rockers.
