You can usually figure axles cost around $350 each. The engine is probably a 4.2L and not a 4.0L if it had a carb. The Jeep looks like it has maybe 3-4" lift and huge lift shackles. The doors and top are probably worth $800-1000. Good windshield frame with glass is probably another $300. Hood, front fenders and grille another $300. Transfer case, maybe $200-300. Tub + title is probably around $500-700. Frame could sell for $300-500, I think. Seats; $200, rear seat; $200. Cage; $150, etc...
Parting it all out is probably worth well more then $800.
