Find a new dealer. Replacement shocks are available at any parts store. I bought the shocks for my '93 Roadmaster Wagon at O'Reilly Auto Parts for under $60 for the pair. Bolted them up, hooked up the hose and was done. I did have to use the ends from my factory shocks on the new ones even though I bought a "kit" that they sell. And make sure you put the shocks on the correct side. They are marked "Right" and "Left". I didn't know that.
The Load Level is very nice to have and there is no reason to go the cheap way out.
