These factory spare tire safety bars were offered for one year only (1986). It will fit MJ LWB trucks with the stock size spare tire. The slotted holes for the J-bolts are already in the frame, so it's a pure PnP factory bolt-on piece. Might work with SWB trucks but :dunno: . I wanted it but it won't work with my 31" spare......
