I have a 1991 Geo Tracker(virtually the same as your sidekick), and when I bought my spacers from Jeff1997....I bought a pair of shocks from the rear of a 1991 Ford Crown Victoria. They were 15 dollars each. Very cheap! All I had to do was cut/hammer/pry out the metal sleeves from the bushings on my old shocks, and shove them into the crown vic shocks. Was kind of a pain.....since I was using very primitive hand tools(hammer... =/ ) Would take about 5 seconds with a decent cutting tool(angle grinder).
