How long does it take for two guys, with a hoist, air guns, and a little bit of experiance of replacing the set of shocks (we both are dismantlers, just figuring out how long it takes for a couple of normal mechanics) on a 98 civic cxi hatch? I am expecting the shocks this week cause i have to do it on that night due to a wedding in my way and the hillclimb i am competeing. cheers
