We do have a radiator shop (which, I am banned from). We also have a gas tank repair shop. Might have two of them, actually. I bet not many people in this crack head town even know that those places are here.
My Wife and I have actually priced getting the radiator in her Buick restored. It's excessively pricey. Better off getting a repro aftermarket radiator.
As for the 34 year old tank from my truck.. well, I only put two patches on it. They seem to be holding.

Also, I took a look at the tank strap just under the cab. Strange design. It seems to have a bracket that bolts to the driver side frame at a 90° angle, then from there a strap wraps around the tank and bolts into a hole in said bracket. Well, it took a minute to figure out how that strap was supposed to go, because mine was jammed up into cab and the bolt was sheared off.

Fixed this by grinding out the rivets and removing the captive T-bolt. Then, found a bolt with matching thread pitch, cut the hex head to fit in that fold, and pressed it back together with the bench vise. Then I replaced the rivets with a nut and bolt combination. Works great.

If this isn't obvious, I had to cut out the rotted through area where the hole for the bolt is, and then chicken **** welded a piece of 20 gauge steel in it's place. Then, used a step bit to drill a hole where there should be one. I kept the original cut out piece there for reference.
Why, you ask. Just get new tank straps. Yeah, right. Find the parts, wait 2 weeks for them to get here, then be balls deep in another impossible project by the time you realize you never finished the first one. Also, while sweat equity is worthless, there's a certain sense of accomplishment in doing the job yourself.
