Tremolo arm - Fender®, for Vintage Stratocaster

Question:
My strat is a 1969 Chicago starburst model. The outer diameter of my tremolo arm is about 4.5mm or 11/64 inches. sorry I cannot be more exact than that. Have you a tremolo arm that is this size. The last arm I bought is 3.55mm in diameter and is too small. CHEERS Tony Charlton, Portugal.
