What size threads for the plastic nut cap holding on the plastics on a 1980 Bally (Mystic) ?

Thanks!

What was original ? Chrome?

Bought two stainless from Home Depot, to see if I like them. HD didn’t have plastic.

Mine are cracked, not stripped.

Stainless would at least match the posts that show chrome above their rubbers.

$20 for a box of 100 at Amazon. Plus 7 shipping. Also comes in nickle.

I couldn’t find it there either.

Was all set to get a bunch of stainless, but I didn’t think about them getting stuck on he bolt. Maybe I’ll stick with nylon.

But the stainless looks so good! Maybe just not tighten them down all the way.

At this point I only have one machine, so the prospect of having to get out a nut driver to change an occasional rubber or lamp isn’t so bad.
