WHat he said, All Grands are uni-body no matter what year. On a side note, when the compact trucks all hit the market in the early/mid eighties the railroad looked into using them for high-rail and other track maintenence uses. Evidently when they bolted up full size high-rail to the Ranger, S-Trucks, and CHerokees the full framed GM and Fords couldn't hadle the extra strain of the equipment while the uni-body Jeeps held the weight (not that it was happy with it, but it held it), unfortunetly the CHerokee got a bad reputation as a high rail because there weren't any light weight high rail partd made for them, so it was thought of as a bad truck?!?! But in the last 6 years in it's production the UP had put several XJ's in that service, several are still running around today.
