A decent used one is your best bet, or one better than yours that would make a good re-chroming candidate. The 350 wheels are WM2 (1.85) 19" 36 hole. There does not appear to be any new ones anywhere in chromed steel. Even Buchanan's don't have them. There are aluminum ones available and with a good polish, would look good, but the ones most places have in stock probably have spoke holes that are too large.
