Disassembling to clean 14deg barrels

Hi everyone

summer lamp maintenance, and the 14deg barrels are cloudy on the inside of the front (large) lens.

(I've not had my hands on them.  . .. )

the crew can't get the lens out.

they tried to undo the screw into the rubber bumper nut, but the nut keeps spinning.  I suggested sticking something in to pin the nut in place, but it's too round (looks like a nylock, but no corners on the nut).  but that didn't work for the crew

I think we could undo the 2 bolts at the back of the lens tube, pry open the back, take the lens out, and reach through, but that seems like a bad idea (flexing the back halves against the rivets).

Thoughts?  or do I need to jam something against the front nuts, but better than what the crew did?

(what's the secret?)
