So, a new idler arm, but what else?

Hey y'all. For anyone who didn't see my project thread, I'll catch you up real fast. I bought a '73 Dart Sport. Didn't run. After replacing most of the fuel system and scrubbing the carb, I got it to run. I took it around the block to find that the idler arm bushing is shot. Like really really shot. I was planning on just ordering a new moog idler arm, but I'm wondering if while I'm tearing into the front end a little bit anyway, is there anything else I should check for?
