I just got back from Dallas PnP. I found an complete draw thru system. The numbers say its off an 81 Riv. Both exhaust manifolds, the upper plenum, the manifold to turbo pipe and the exhaust head pipe were all there. I didn't see the lower plenum (intake manifold) but it may be in the car still. Even the air filter housing was there. If theres interest I can go grab it and ship it for someone. The car also had a set of hedders for an H-body but they might work on a G and A Weiand single plane intake. It looks like someone was running this car around as a 4BBL with hedders, then was going to swap it to the turbo set up but didn't quite make it. Heads were in there a fresh crank as well as a new GM turbo cam. The turbo had a reman for GM tag on it. The cam and crank had surface rust of course. Message me for info etc
