I just bought a 91 comanche 4.0 HO, 2WD. I found a 98 cherokee 4.0, 4WD donor. Off the top of my head I'll need the transmission, transfer case, front and rear driveshafts, 4WD shift selector, front axle, and I'm assuming the main wiring harness to accommodate the trans/transfer case. So my questions is, will I encounter any problems since the comanche is a HO and the cherokee is just a regular 4.0? Also, is there anything else I should be aware of or require? I also plan on taking the grille to update the front end appeal. Thanks.
