Default YS 91AC needle valve

I misplaced my needle valve on a 91AC. Centralhobbies only lists the complete needle system for this engine (needle, housing, seat, o-rings, detent spring, etc), but mentions this is the new version for the 91 and 1.20. Unfortunately this is out of stock.

is the bare needle itself for the 91AC used on any other engine? They have the needle for the 1.10, the FZ 91, and a few other similar sizes, but they all have different part numbers.

Is there an interchangeable part number for the needle on my engine, or am I stuck waiting for and purchasing the entire assembly?
