it will bolt up right to a 16T after you drill out the holes for the wastegate tomount to bracket. You have to use a different rod to mount it to the 19T. The rods on the wastegate are interchangeable. It's a Forge FMAC048 wastegate actuator for a T3/T4/T35 and it's adjustable. also, on the 19T, the wastegate will hit the CBV housing if you don't file some material out, it's an easy fix w/ a round and flat bastard file.
