[Milsurplus] Is This a Nutty Idea?

[Joe Connor]

I'm working on a Navy RBM receiver with badly leaking bathtub caps. I don't want to restuff them because who knows what toxic stuff lurks inside, and I'd like to leave the original bathtubs in place. Because of the way these bathtubs are mounted, desoldering the leads is a real pain, and there really isn't any room on the chassis for terminal strips. 
Several of them are three-cap units with the caps grounded through the case to the chassis. Here's my possibly crazy idea:
1. Replace the screws and nuts holding the bathtub to the chassis with nylon screws and nuts;
2. Use a nylon washer to physically isolate the bathtub from the chassis; and
3. Hang new caps on the three lugs on the bathtub and ground them at a convenient point on the chassis. 
Will it work?
As always, thanks.
