Ride Tech Shockwave bushing/heim

[wedged]

Has anyone replaced the urethane bushings for heim joints on the shockwaves ? The kit i am installing (it's new, but about 4 years old) in a Mopar B body had bushings top and bottom. The car doesn't even run and from moving around the shop and up & down on the lift, the bushings split and fell out. The mounting points don't stay parallel through the full range of travel. I want to put the heims on one end and keep the bushings on the other. I can't find any info about removing the one end to install the heim joint.

I found the part and it looks like it's held in by a snap ring. I just don't want to ruin anything replacing it. I may just send them in.
