I have a set that need rechroming that are in good restorable shape.
When I needed some I looked forever - it seemed like and couldn't find any that didn't need complete restoration and even those were in the 100 dollar a piece range. As you know they are very thin, so you can't sand or polish on them too much before you go thru metal. I'd sell my extra pair if you're interested, PM me.
The dog leg pieces are what I have which are chrome. The other pieces are stainless which gets polished. 55's I believe are different-No sun visor attachment area. Makes them more scarce.
