I got my replacement speedo today (thanks Malloy!) - works perfectly.

I noted the mileage on the old one when I removed it, and the mileage on the new one when I put it on. Beyond that, I really don't know what I'm supposed to do, legally, to track the difference (new one is 6635.4 miles less than the old one)

It's nice to have some idea if I'm going to get pulled over or not.....

Now I can move on to the chrome bits I want - and a front turn-signal re-lo.

...you're gonna feel a little pressure....
