'76 Dart Lite -- Budget Boost Build

I also need to track down a stub of 5" tubing, to make the down pipe snout. The turbo is internally wastegated, but it didn't come with a down pipe. I have no idea what the stock down pipe looked like, but there is a nice flange surface. I am going to take some cardboard, make a gasket, transfer it over to flange material (mild steel, bought with other metal), and take a scrap piece of 5" stainless (I work in food industry for next week), and pie cut it to taper it down to 2.5, so it can handle the wastegate feature, and have 2.5 snout for exhaust to connect to down the road.
