Your link works, I looked at it, the compatibility chart shows it fits 22 vehicles, all Tri 5 Chevrolets.

The link to the installation instructions comes up with nothing available.

The pictures in the listing do not show a typical triangulated 4 link like GM or Ford have used for decades. More like a splayed foot 4 link.

The listing is too skiffy for me to consider it, I get an itch between my shoulder blades reading it.

It does say, at the very top of the listing "Upgrade Today! Coil Overs Not Included, Save $$$!!"
