Scott : Interesting. When you note "Option" are you referring to "Factory Option", or are you including "Dealer Option" ? To avoid confusion, I usually try to avoid using "option" to include "Dealer Option" as a Dealer Option is just an Accessory Installed by the Dealer. In which case, it could be installed on any Model, including the XR-7's. Of course if all XR-7's came with the Safety Convenience Package (I am not that familiar with Cougars to know that), then it would be kind of superfluous.
It is interesting that the light assemblies are shown as different on 67's and 68's (C7ZZ- and C8WB-), as the lens'; and sockets appear to be identical ; I guess just because of the ring end versus the bullet connector end, especially since the 1967 description notes it as "Lamp and Wiring" ?
Thanks for sharing this.
