Strut rod bushings

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!

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.
