My Dart Swinger Project!

What other bottom stuff do you think I need?? From the doors up everything underneath is gonna be brand new. The rear end I'm not really gonna mess with yet because I have the 8.8 I'm gonna put in it.
I could go ahead and drop the tank and clean it and check the sending unit. The exhaust is new. The rear shocks and springs getting replaced with the 8.8 so no point in doing that yet. So frame connections and gas tank. Anything else I'm forgetting?
how is all the frame work.... in the back where the leaf shackles mount?
