Chromoly bearing retainer plate for the A520
This is the same piece for an A-555 IIRC. (Just sayin' in case you ever come across one.)
Old school Grainger valve MBC.
One of the greatest thing about the Grainger valve that surprises many people is how much harder the boost will rise, even if you dial it in for stock (or near-stock) peak boost. Most people don't realize the OEM computers begin cycling the boost control solenoid after only a couple pounds of boost--the engineers did this in order to 'soften' the boost rise and minimize the torque 'shock' to the transmission. The Grainger valve does away with all that nonsense, and lets the boost build right now. It's fun.
