SQUARE BASE LOWER CONTROL/UPPER CONTROL ARM BUMP STOPS oem

that WASP stuff from Oz is current. probanly made in china but the aussies sem to be quite good at getting decent quality out of that country. the parts over there are often double the cost you would pay in US so somone somewhere is making a bit more $$$ and putting in potentially a bit more QC .

ac delco 45g5002 upper bumpstop has square bit

1973 DODGE DART 5.2L 318cid V8 Bump Stop | RockAuto

not seen a lower with square part. not sure the lowers need to be torqued too tight, they just need to stay in the right place with the right orientation i.e some tension to pull the base rubber into contact with the metal. just do up the nut, short spanner tight. Or clean out the treads with thinners and a die if need be, they are sometimes gummy and full of crap. Plain nut and spikey or split washer, or mild thread locker works ok instead of the nylock. Overly stiff nylock and crap in the threads might cause a problem. just run the nylock down a different bolt a few times its locking-ness will be compromised somewhat but hey..makes little odds here.

uppers appear have the square section on most shown in images on rock auto, should have no problem with installing them. getting the things off is the bit that casues more of an issue. when rusted that square bit rounds off, and the mole grips are needed or tack weld a bar to the square head onc the rubber snaps off provides heat to get nut undone and leverage.
