[TR] Tr4 speedo

[Lee&John Howard]

After 6 years of not knowing how fast - or slow - I'm going it's time to fix
the speedometer. It now indicates faster than reality, and increasingly so
at higher speeds. The car was originally non-OD  but I switched in an A-Type
OD during the rebuild. It may not be exactly right for my 64 TR4 - it may be
from a 4-A - and has a serial number of CT24212.

I've been thinking I installed the wrong speedo drive, but looking at the
Spare Parts Catalogue they look very different and probably not
interchangeable. I do not have the 4A angle drive.  The OD doesn't call for
a special speedometer, does it?
