Keep in mind that the 1280 O/D speedometer was not used throughout the
4-synchro MGB cars with overdrive, in fact I believe it is a 1971-1972
speedometer only.  What prompted our research into the matter was when a
coworker's 1971 B was converted to overdrive, and we couldn't find the
appropriate speedometer anywhere in our stock.  Then Paul Barnes' most
excellent 1972 MGB with overdrive was used as reference and still after not
finding any differences, the three of us finally gave up and called
Nisonger... which is when we were informed that it is only a face change.

If I venture into work over Holiday break, I'll do a write up or
something... one month off and I'm already bored 4 days into this vacation!

Any wagers on how many phone calls the poor receptionist at Nisonger is
going to get about this?  ;-)  Its an epidemic I tell you!

BTW, Phil I think the company you mean on the West Coast is CARS... another
division of Moss along with Nisonger (there are two Nisongers too, the other
is not part of Moss Motors).

Happy Holidays,
