Hey. I know CJ Pony parts carry an intermittent wiper switch for 65-66, 69-70, and 71-73, but I couldn't find it for a 1967, sorry. I'm not sure how the 67 wipers and squirters work, but I know on the 66 you pull out on the wiper knob and turn on the wipers. The resevoir will be either a bag or a plastic container mounted on the driver side front inner fender.
1966 Mustang Sprint 200 "Oliver"... factory fog lamps, factory rally pac, off the road for restoration.
2005 Mustang 4.0 litre... Airaid CAI, Honeycomb taillamp panel, more mods to follow.
