Jim Murch of Reno-Tahoe Panteras built a few wiper delay systems some years ago that works with the Pantera's Lucas system. The control box is about the size of a matchbox and spade-lugs into the stock wiring. They were all on '71-72 Panteras with rocker switches, but I see no problem with adapting it to early rotary switch cars. The model was a wiper delay system once sold by JC Whitney (discontinued) that Jim modified to work, then duplicated from components when JCW stopped carrying the accessory. There was an illustrated POCA newsletter article done on it.
