Bookmarked. Very useful post. I didn't know that strut rods varied over the years. I used the Moog 2-part strut bushings in my 1964 & 65 A-body and 1965 C-body. Didn't know there were various Moog PN's. I bought PN's listed on rockauto for each car. Seems I overtightened one on my 1965 Dart, trying to get the cotter pin hole past the washer (couldn't), since I found the rubber bushing split a year later despite not even driving that car. I find from post 16 that it has no hole for a cotter pin, just a jam nut. I recall a cotter pin and castle nut on my long-ago 1969 Dart and my C-body. I replaced the worn bushings in my 1969 with the 1-part one, which was very challenging to press into the hole so was thrilled to later find the 2-part one. Time to revisit on all my Mopars.
You don't want to move the LCA back since that takes away from caster, and we need all the caster we can get for radial tires. You want the lower ball-joint as far forward as possible and the upper ball-joint aft to gain caster. I have seen after-market length-adjustable struts, which I recall have a Heim joint at the front instead of bushings. My 1985 M-B 300D has instead a rear "guide-rod" which pushes on the LCA instead of pulls (I've seen the Mopar part termed "drag strut"). The M-B one has a length adjuster (like tie-rod). I think the pivot point on the K-frame is similarly a rubber bushing (behind steel shell) since I've read it can fail.

Hello, everyone,
I need to change these strut rod bushings on my Dart 75, I bought this Kit K7040 and I have a question, would it be possible to change these bushings without disassembling the lower arm?
I was thinking about removing the pressure from the torsion bar, loosening the nut spherical joint... Does anyone have a tip?
Thanks and good sunday to all!

For anyone who would like the original 1 piece design, I have a couple last sets of *** N.O.S. *** U.S.A. made *** Strut Rod Bushings.....
Not big $$$ , because as some note , they are more problematic to install... I would just rather see those people look e who want them , get them.....
P.M. me, as per forum rules, if interested......Craig.....

K7040 is for the '67-72 strut rod design, it will not fit the '73+ course thread strut rods correctly because of the differences in the shoulder location for the bushing.
For a '75 you need K7068, but they're no longer being reproduced.
Well, I never knew the late A body strut rods were longer and had different threads. Not too long ago, I had to replace the bent strut rods on my 65 and dug around my stash until I found some. I couldn't remember what car they had come from, but thought they were probably 73s. So now I had to go out to the garage and see if they were fine thread or coarse thread. Thank goodness they were fine thread. So they obviously were pre-73. However, they did have provision for a roll pin which my original 65s did not. I put roll pins in, and also used the two piece bushings.
