As explained earlier number #3 position. number 4 position is just in front of rear axle frame has a slotted hole in it....use a small flash lite or your hand to feel the body mount bolt and feel if a gap exists between bolt head and base of frame...if so you have no lower bushing....position 7 is easy to spot as its by the rear bumper very visual one side is slightly different position than other side...
Point being if you are missing one under #3 the center of the door 99% certian you are missing #4 and about a 50-50 chance #7 is missing.
#5 is not really considered missing as only the GNX got them and that is alittle tougher to install...however 3-4-7 lowers is something you want to install the longer you wait the tougher it can be to remove the grade 8 bolts and the better secured your body is to the frame....
