True but the middle one (1-59/64) will work on both the 72 and 73 ball joint but not the hd truck,according to the manufacturer I purchased mine from anyway, but I only used it on a 74 so not sure($130 list it should do laundry too) oh and you will need a 3/4 impact to get it in as they are not actual threads so much as teeth for digging in to the arm
