IIRC there are measurements in the Factory Assembly Manual. John
Correct. Per Section 1, Sheet 1.07, top of frame is 10" above the zero line, and top of floor is 11.88" above zero line.
Also Per Section 1, Sheet 3.12, the rear body mount shackle should be shimmed to "maintain -.76 +.06/-.0 Dim between floor panel and top of frame."
But if there's so little space, the rubber bushings in the body mount shackles are probably severely worn.
