I'm at the point that I want to install an exhaust on my truck before I get too much of the body installed. It's a 49 AD 3100 with a stock 216. The original exhaust was almost non existent so it was scrapped. Looking back I wish I would have kept some pieces. I read that the stock size off the manifold is 1 7/8". Does anyone know where I can get the initial 2 bolt flange to start building off the manifold? Will a modified 2" flange fit the original 1 7/8" manifold? I can't seem to find much online other than a full system on Chevs of the 40s.
