Where to find 20" Weds Borphes Kranze center caps?

Does anyone know here I can find all 4 for the 20"?  If not what size are the center caps and will be the new Kranze center caps fit?  Thanks in advance bros....

best bet is to just order them from Weds directly.

You're going to have a hard time finding them used. 

If you want to measure the size cap you need I'll measure my Kranze ones to see if they will fit.
