I can`t help you with the shops.
I was in Portland all last week, so I hit 3 of the LKQ yards looking the inventory over.
I did notice 2 83 300D with good tight turbos. I felt the input shaft, turned good w/o any up/down side play. most have a good amount of play.
I would have pulled them, but was short of time. think they are around $60.00.
This was at the damascus yard out on Sunnyside off 205.
As I was leaving they were just setting a 81SD in line.
