I've got an '06 Liberty and it's amazing how many of the fancy-schmancy things can be broken and it still putters along. I was collecting lights on the dash until I decided to just tape over the leds.
there's always the chance that changes were made to the design over time that using a single part as your basis for manufacturing could miss. lots of other stuff was changed between 87 and 88.
