Hatch Set Bolt Lock

[Erik R]

I'm looking for 2 of those spiral plastic knob set bolt locking mechanism for a hatch. Like for when you raise it and you want it to stay in a certain position you lock down the bolt with a plastic spiral knob. My main hatch above the bed in the master stateroom is missing both of them? any ideas? part #'s?

Here are the arms, knobs(PN-1721-$12.47/ea), etc. There are several threads on here addressing replacement of the arms. It is not exactly as easy as it should be due to the rivets on each end. However, maybe the knobs simply screw right in. I have never tried removing them.
