Nick,
$10 consider it sold! I will probably hook up a mechanical gauge for a bit, just for a sanity check. Don't you want some shipping thrown in there too. I'll send you $20 to make sure that shipping is covered. PM me with your address and I will put a money order in the mail on Monday. I replaced the switch, I really don't think it will have any affect on the gauge, but it was only $12. So it can't hurt to replace it. And while I had the tire off, I noticed that I had a brake pad that was totally shot. I should have seen it the other night when I was messing with my auto hubs, but I was so focused on the hub I did not notice that I had a pad that was almost completely shot.
Thanks,
Kris
