I need a part - the front vacuum actuator for diff lock

[SJ]

My vacuum actuator has a small leak in one of the chambers. This is the
gizmo on the starboard side of the trans that shifts the front diff lock in
and out.
Its item 3 on the FA, they call it the throttle control element, part number
857 711 997. No, I dont know why the hell they call it a throttle control
element.

Patient is 88 5kq.

Same part is used in:
85 - 87  4kq
87 - 88 5kq
86 - 88 5kq
VW 85 - 88 Quantum Synchro

I havent priced the part yet, will do that tomorrow. Maybe one of you guys
has one laying around.

Yeah, that "where used" listing is slicker than snot.
