Can anyone suggest where I might obtain a set (5) of new after-market tire valves to fit the 14" Bundt alloy wheels"? OE cost for SS is prohibitive...$179.70 at MB dealer in Canada...EACH!! I see lots of the refinished Bundt wheels on the net (Bring-a-trailer), etc.with new black valves (not the SS kind), so I know they're out there. Help!! Thanks in advance!
