I have a '95 it is not the rio grande but mine was the ax5. I think as long as it is a 4 cyl. then you should have the ax5. I just did a lot of digging into it recently because I just finished replacing mine.
'95 wrangler, SQUARE HEADLIGHTS, 4 cyl., 5 spd., 4" superlift w/rancho rs9000 series shocks with in dash controller, 2" body lift, 35x12.5 15 tires
