There is nothing in texas law stating that you must have a speedo or odo. Not to my knowlege anyway. The car is "exempt" mileage wise because of the age, so the odo doesn't matter.
For a 91 it is very very basic. No emissions check. You have to have a cat, muffler, blinkers, headlights, brake lights, license plate light, horn, and safety belts. Thats about it. Well, other than no illegal modifications, like being slammed to the ground or 5% window tint, that kinda thing.
And my inspection guy has a serious hard on for CRXs.. Rural texas has one good thing going for it.. All the inspection guys just don't give a crap. Except for major chains (wal-mart, firestone, etc..) They will fail you for being 5 psi low in one tire. And then charge you for it.
My transmission is missing the speedo/PS assembly.. And I haven't been able to track one down as of yet.. If it had that, I would go ahead and grab an autometer speedo and toss it in there. But as of right now, I need the assembly as well as the gauge. More trouble than its worth, as it would be easy to figure out what RPMs are what speeds and just cruise by the tach.
Shift light is programmable, so I could easily set it to come on at 72mph in 5th or something. Then re-set it for track days. I dunno.. Thats another back burner thing, I can do without it.
