kind of reminds me of a Schwinn speedo?

You'd be better off getting a new, similar style tach from Summit Racing.
Or no tach at all.

That's how I've been driving mine. I come from the ACVW world, where nothing ever had or gets a tach, though the speedo was marked with shift markers for redline.
I've figured out that 25 in first is loud enough to shift, 45 in second (if accelerating hard), run third for a little bit, then drop to 4th for anything beyond 60 for extended periods of time.
When I first started driving it, I googled the trans ratios to do rough calculations on shift points, and the M40 ratios are pretty funny.
1st 3.13
2nd 1.99
3rd 1.359
4th 1.00
But I digress.
