No. 4 carriage latch spring in pieces :'( … looking for replacement

Hello! One of our No. 4s has a shattered X-10161 spring causing the carriage to not catch on its return to the feed board. The spring holds up the carriage latch (?) that the carriage needs to catch. I attached photos of the broken spring, an identical intact one on our other No.4, and the diagram from the Vandy manual. Anyone know where I could find a replacement spring? Thanks :) — Gabi @ UT Austin

Edit: I just looked under the Carriage Latch category and see that it is maybe the QRS-6 spring that we need.
