4.0 L Jeep Engines?

You can usually find seats over at NAXJA.org on the colorado for sale section, or checkout the junk yards. I noticed you had the sunroof... those are pretty rare on the cherokees... And for sure you have coils up front leafs on back. If you load the back with stuff you will prob notice the sagging as this is very normal for old cherokees, the rear leafs are most always shot.
