Thanks everyone for the suggestions regarding tach and speedo issues. I just
called Nisonger and after describing the symptoms the gentleman there said
that this is often due to the instruments losing their magnetism and the cost
to refurb both clocks will be $175 each, more if they also need new glass and
bezels.
I missed a few on eBay and they seem to go for around $100 and you are never
sure what you are getting so I think I will plan to ship them off and get them
inspected, cleaned and refurbed.

I agree, and in fact I'm pretty sure that's the problem I have right now with
TS13571L. But disassembling the gauge to reach that bearing is kind of a
finicky operation; last time I tried it, the shaft broke before the pointer
came off. So if that is the problem, you might want to consider sending it to
a professional instead.
In case someone hasn't already supplied it, here is a link to Tony Rhodes'
excellent article on speedo repair:
