Need some tool box advice for a Longhorn

[laplander]

When we brought our 71 Longhorn home, we knew the toolbox had rusted out underneath like most of the boxes do, but figured I would try and save it by buying a patch from anohter one. It turned out to be as bad as the one we had. Any of you Longhorn guys run into this? Did you just get a regular patch and do away with the tool box altogether? That's kind of where I'm leaning and could use some input on whther it's a mistake or not. Here's a pic of what I'm talking about.
