Well ... I won't speak for the TR6, since I'm not entirely certain
(well, I wasn't, but do read on), but the 4A definitely uses a
longer speedo cable for overdrive than for non-overdrive. Since the
TR6 gearbox is the same unit (at least the early, A-type O/Ds are)
and the speedometer is in the same place, I'd guess that they do,
too.

Perhaps I was speaking a bit out-of-school when refering to the TR4A. I
thought that the notch in the floorboard for the longer cable that
emminates straight out of the transmission was deleted at the same time the
hand brake was relocated to the driveshaft tunnel. But without this notch
there is no room for the cable to be run straight out of the transmission
and the right angle box is required to fit everything within the confines
of the transmission cover. You are right in that the transmission is the
same but with the box, the cable hugs the right side of the transmission
and if you route it over the top of the transmission, the stock cable
reaches the speedo head quite nicely.

57 TR3 (w/A-type and longer speedo cable that makes a nice generous loop
under the right hand side foot well floorboard before going over the top of
the transmission to the speedometer)
71 TR6 (w/J-type, right angle drive and stock cable that runs over the
transmission to the speedometer)
