Well, first off, that's not a Thunderbird turbo...if it is, it sure does have an oddball turbine elbow on it because that's not the kind my T3 from an '84 Turbo Coupe has. Also mine doesn't have an adjustable wastegate stock, and overall that turbo has some oddball looking stuff about it. Of course, being that it's a parts store replacement, maybe it doesn't have all the same parts as the factory turbo. beats me.
That is one weirdass turbo. It doesn't have a T3 2-bolt inlet flange...I dunno what the deal is with the turbine-manifold flange, doesn't look like any standard flange I know of. At any rate, I'd stay far away from that thing.
