the way to get the plastic cover off is with a couple of butter knives. Pry
slowly and gently completely around the edges a couple of times at which point
it will have loosened in places, and continue until it comes off. You will
probably
break some small portions by the mating edges but this will be minimal. I
have been
able to reglue all so far with garage man schmuck. Record the position of
everything 
both before and after you make any moves. Every time I've done this, I ended up
back at the same point I started.

DON'T SAY WHO TOLD YOU!

Why do you guys insist on reinventing the wheel? Ever heard of a motorcycle?
Kawasaki zx11 speedo goes to 175 I believe, is that enough? I'd think that 
one could tie into the digital motorcycle speedos for reference to a cpu.
They drive off the front wheel, in fact I've even seen cars that the speedo 
cable went the spindle and was driven by a hole it fit into in the dust 
cover.
`
If 175 mph isn't enough I'd start looking for airplane parts.
