I think a medium sized GPS boat speedometer would be a perfect
addition to a pre-L Pantera since you can't read speeds under 80MPH
anyway.  The boat meter only goes to 85MPH, but it doesn't matter much
after that speed in most cases.

I like the in-line gearbox for L Panteras though.  That seems simplest.
