Typical inner fender rust holes, do you ignore, fix, or replace ?

[Green Machine]

My next project '70 C10 has a real nice front clip, including rad support has no holes under battery. Inner fenders have the typical rust holes by front brace. I really don't want to replace them because of expense and all the bolts likely to twist off like they did on my '68. This will be a nice truck when done, more of a driver than show truck though. Can you fix the holes easily so it looks nice ? or just pop rivet on a patch (I don't weld), or just paint the tubs and ignore the holes ?? I will be removing the entire front clip as an assemblly for general cleanup, and spray can paint tubs and support anyway.
