the driver seat in my 99 Xj is about 5 good left turns from ending up in the back seat, so new seats are in order. ive got my eye on some mastercraft rubicon seats and obviously some 5 point harnesses. my question is can i still safely use my factory belt with the mastercraft seat? this would give me time to get a cage, possibly D and C, modify so the seats are mounted in the cage and properly mount some 5-point harnesses. thanks in advance.
