Should I or shouldn't I?

:?:?Working on disc brake swap-over on my 72 Valiant...now that stuff is opened up I'm considering control arm bushings too. The car will just be for driving, cruise nights, having fun....not doing a restoration or performance build. So...how much of a can of worms am I opening? I already don't have as much time as I like to work on it...but it's half disassembled already...any input on the pros + cons would be appreciated
