I'm working on a few engine bay details on my '66 fastback, built December 8th, 1965, in Dearborn. The car came with 2-speed wipers. At some time in the past, a previous owner removed the windshield washer pump and mounted an electric fuel pump in its place. I now have four holes in the fender apron, but I think the washer pump originally only used two. I'm trying to figure out which two holes are original holes and which two have been added by the previous owner.
Could someone post pictures of the correct original location of the two-speed washer pump? Thanks for the help!
