I may have a spare cluster with the parts, but not a free minute to look until Tuesday. Hopefully you just need to slide the knob onto it.

Only $55 at Pelican. I've seen little plastic bits for aircraft that cost less. Maybe eBay or someone else on the forum can send one. I'll see if I have a few in stock on Tuesday. I might be rich!
