Re: What does this mirror fit?
Your part number is for a 1966 full size Ford, but can't say if its for the plane jane sedans or for the Galaxie series up to the LTD models. C = 1960's, 6 = 1966, A = Ford, Z = Ford parts & service, 1766 = basic part # for all Ford product mirrors, A = design code. If it was a B it would be a design or modification change. If the 6 is written over with a 0, that would be for a 1960 Ford, can't tell you what the 2nd '0' would be. If the part # started out C6ZZ, that would indicate mustang.
