What's in Phoenix?

Hey guys....I am going to Phoenix for a couple of days, never been there before...I'm thinking I should bring an extra suitcase with me and pick up some rust free parts while I'm out there for my 65.....I can't get anything too big, parts would have to fit into a suitcase so I can get some free shipping (I'm not paying for the trip). My 65 Vert is pretty solid...except for the rear quarters being rotted out at the bottom, which I think is pretty common....I wish I could get rear quarters, but I'm not sure if I want to get small patch panels (to fit in the suitcase) or just wait and spend the big $$ some day on full size quarters....so long story short...where should I go to look for parts?
