[FirstOwner69]

My early 69 has it mounted on the radiator core support above the voltage regulator also. The washer bottle bracket for the core support mount is also slightly different from those I've seen for mounting on the fender in order to stand out from the core support enough for it to clear the top of the core support. Here's a picture showing the 2 brackets. The one on the right is the one used on the earlier model years, and the one on the left is the one I've seen on the later models with the fender mount.

Which bracket do you have? Bet it's the one on the right.

See additional picture showing it mounted on the core support in post 7 below.
