For the RB:

Assuming that the cluster works, send the tach to Carl H and he will mod/calibrate it to work (I think he can do the '89 tachs). And then pick up the Dakota Digital speedometer calibrator thing and wire it in before the cluster. I have both things done to my HUD and will be attempting to calibrate my speedometer tonight.
