Not sure what its called but I'm looking for the gold c clamp deal that bolts the center section to the compressor housing. When I went to an external wastegate I pulled the stock gate off which was welded to the piece I need. Anyways its for a TA-54 turbo. Not sure which ones all fit it. I'm sure there not worth anything and probley cheap. If I remember right there is like 3 that are on the turbo.
