It's exactly what is says, an adapter that went on the speedometer gear at the transmission which was required with the steep rear gear you have. An automatic 2+2 would have come standard with probably a 3.23 gear.

BTW, wonder why they missed the Turbo Hydamatic transmission on your window sticker. Or did I miss it?

This is my dream car! I hunted for one for several years to replace the one I restored back in the 80's and couldn't find anything I wanted. I found some nice 4 speed cars, but no automatics. Finally settled for a 65 GP, but it is no 2+2. I you get tired of having fun with it I'd love to have a shot at it.
