70 Dart, new in town

Hello all, figured I'd make an newbie post. Just picked up a 70 dart swinger. Supposedly has a 318 in it now, I have the original cracked 340 block. Needs some body work, but for what I paid, I couldn't be happier. I'll be around picking some brains ;) Like how in the world I'm going to get exhaust on the left side, right side has a glasspack and some crappy pipe, left side is open manifold. I'll get numbers off of it sometime. Hope y'all like green!! I have first startup vid after 15 years of sitting, but can't seem to get it uploaded.
