i have made this swap on a 1990 , 1993 &, 1992 models. the gauges worked with the sending units that were there. the only issue i ran into was the speedometer. some are cables, some are electric. once you figure out what you have then you are good to go.

i also, installed a second set of gauges as a back up. its also a good idea to put in a tranny temp gauge.
