Jerry all of mine are distorted from heat. The problem with the 51-54 lock knobs is that they fit over a thin, flat barbed bar, and not a round shaft. So that is why you can't ever use an aftermarket generic knob. Once the are pushed down over the barbed bar the only way to really remove them is to use a heat gun to soften the plastic enough to get them to pull off them off. It's a design I never understood from Packard.

If someone has a good one, perhaps we can get some picture and measurements for Jerry. I can take pictures/measurements of the barbed shaft. But the knob itself is pretty simple/basic in design.

I am half temped to see if I can get someone to machine them out of metal with a set screw!
