Was Service Counter Standard on TR6

[Bob Fabie <rmf3860@erols.com>]

I have a '75 TR6. If I have a service counter, I don't know where it is.
What I do know is that the speedometer cable seems unnecessarily long,
but the only other one I know about is the two part cable which connects
through the "service counter".

So, what are these service counters and do I need/want one? Does anyone
else feel that the speedo cable is too long?

Thanks
