Recently sold our '93 XLT and still have our '94 EB. The '93 had 5 digit, the '94 has 6. The '93 had an R12 AC system, the '94 came with R134. The serpentine belt tensioner is different (arm pivots the opposite direction) on otherwise identical motors.
Was also a slight difference in the interior panels in the cargo area, where the cargo cover attached. The EB has slots molded in the panels to hold the roller, but the XLT used an additional bracket screwed into the panel. Might have been a difference of cover was stock on EB and optional on XLT, but seems like a lot of hassle to make two different panel versions...
