For 1990, the W460/W461 was extensively revised, and a new chassis number, W463, was assigned. W463 moved G-Class from the spartan and utilitarian towards the luxury spectrum while maintaining the off road ability of the original.  The 463 has had a LONG run of production with many variations.  If you don't find what you are looking for, open a support ticket and we would be happy to help you out.
