Strut rod bushings

however
moog used to do two versions of "Improved design" (2 rubbers 2 washers + hardware)
to allow use of multi part kit on early and late cars

Part No: K7040 looks like its a split pin no steel sleeve design for 67-72
wind on your castle nut until you can fit the pin

and they used to make a set with much the same parts as k7040 with a steel sleeve included
and a ny-lock nut instead of the split pin/nut
in that case you used the steel sleeve and nylock nut, wound on tight against sleeve regardless of if you had a hole for a split pin or not.
this in turn catered for 2 types of later strut rod one with split pin hole and one without. Not to be confused with the short thread early rods.

they catered for the two different styles of strut rod, with different thread lengths, with a "later" style, multi-part kit for both types and ages of car

so you didn't have to use the 1 piece kit

I can't find both versions anymore
