Review on ACDelco 45H2133 Professional Rear Spring by Shaylon Bateson

I installed an air spring conversion kit a few years ago. Included was a set of springs that appeared to be compatible with the messenger. As you can see, they're about two inches shorter than GM's suggestion. This resulted in me blowing 3 rear gear seals before realizing the gear angle was wrong due to the shorter spring. Do yourself a favor and buy them and save yourself the headache of figuring out why you're not buying cheap.
