Any one remember the size of the valve stem hole? I gotta get one repaired. TIA

Forgot to mention, it's a 28" PA

I believe it's about 5/8" or so.

I seem to get asked to fix many of these so whenever someone in my neighborhood throws out a rim with a good section around the valve stem I cut out a 8" square to use as a patch panel for the next repair. I went out and measured the few I have in my donor pile. As mentioned before, they all measure 5/8" in diameter.
