On the 1972 Six Day were the number plates steel ? {the round ones} And were they aluminum for the 1973? Or did the factory use both at any given time . I have a 1973 with a aluminium plate for under the pipe side and a steel one on the forks . [?][B)]
(that I know of) They were always steel. Later on......what year was that, maybe '75-ish ?, the front ones became plastic.
Rob and Larry,
My 1974 1/2 Six Day has Plastic on the front.
