HA HA HA, no you don't need a gas system to run KYB's. You read way too much into stuff. The KYB's are gas charged instead of oil filled.
www.pfyc.com used to have the sturts in a kit of 4, but it's under the Grand Am store if they still have them. Otherwise, look up KYB GR2 on Summit Racing for the Alero but there you will have to buy them as "each"
Do all 4 at the same time
