Along this thread, how fast are people driving their diesels?  I've got a
'82 w/4spd 7 passenger.... assuming a tailwind, I never have taken it over
60MPH... is this about what others are doing, or is this too fast??  I
understand there are differences with tires / inflation / speedometers, but
in general terms....
        Has anyone installed a diesel tach successfully?  How difficult is this?

Thanks,
Chris
