The re-designed frame assembly for the new S/T Utility is a mild, steel hydroformed frame assembly. A front frame service section consisting of the left and right frame ends, body, and radiator support mounting brackets and front connecting cross tube is available. If damage permits, locate and cut off the front 420 mm (161/2 in) portion of the frame using the die-mark indicators as a guide. The front and rear body mounts, radiator support mounts, steering gear and transmission cross-member can be ordered and replaced separately.
