/^Blackmagik^\ Some of us aren't that good around a set of tools or have the tools readily available to get the job done right. Rather than mess up a $600+ purchase by f*cking up an installation, it's better to have someone do it professionally and blame them if it's messed up.
momo, you're getting jobbed. That's too high in the LI/Queens area. Most places along Northern Blvd (the Asians and Spanish places around Shea Stadium) will quote $50 ea shock/spring. Go to any Sears Automotive about a month later and get an alignment for $60.
The total installation should run you $250 + tip for the crew.
If all else fails, try Midas/Meineke/AutoZone.
