Rallyes with trim rings used extensions on regular valve stems, so you can get an air chuck on them.
Seems to need 1.25" total height according to some guys, 1.50" according to others.
IIRC, the extensions had white centers, but whether dead-correct ones are available, I don't know.
If it doesn't have to look stock, and the trim rings move around, that could be an issue unless the stem have a steel jacket.
It's been a LONG time since I had trim rings on anything, but I remember Dad's '66 Sport Fury's wheel covers would rotate and cut into the valve stems.
The stock hubcaps on my 51 Plymouth does this. Chrysler made chrome valve stem covers to fix that, still available. No idea if they'd work on a trim ring though
