[R-390] Panel meters again

I am looking for replacement panel meters for my 390A.  Not original, but more modern meters that will fit the holes.
I notice there have been very long threads on this subject many years ago (the thread I have is dated 1999, hundreds of posts), which really didn’t seem to resolve much except the specs for the meters.
Wondering if anyone found a source they like lately.
(the meters on the restoration I am working on are in pretty bad shape, but I am rebuilding them to keep as spares)

I found this company that makes a great looking replacement for the line level meter, but I am not sure they are actually available:

ebay has a zillion sellers of various conventional analog meters, most very inexpensive, but didn’t see one I liked.  It is fairly easy to modify the meter for the correct scale, and put a new printed scale on it (done it many times), if I can figure out the actual range of the meter movement (for example a labeled 0-100V meter is probably a 0-1 ma meter movement with a scaling resistor inside the case).
