I'm confident that you can get a match here but to get it "right" they'll need a color code.

Start here for the '89 Jeep:

Check out the "Locate Color Identification Plate" link:

and

"verify: your color code link:

Good Luck!

You will need to either borrow our color books or visit a body shop to see if they can find the color code. Interior colors are not coded on the car anywhere and the only way to find them is to compare the color with interior color chips.
