your sway bay needs to have links in it, as installed it will not work. your suspension will not move at all.
both ends are locked in rubber mounts; one end should be locked in and the other end should have some kind of link to allow for differences in the pivot point of the spring ends
as installed you have a triangle locked from the 2 sway bar mounts and the spring pivot
most sway bars can be mounted 2 ways on a straight axle, secured to the axle with links to the frame or secured to the frame with links to the axle
independent suspension requires the sway bar secure to the frame with links to the individual A arms
this is a stock task force suburban front sway bar: sway bar on axle with links to frame
sway bar on frame with links to axle
most sway bar links are of 2 types; straight and dog bone
i tried to find an example of a link that would work with your set up and did not find a cure
