Are the mounts & springs with Monroe's Quick-strut package of good quality? I'm debating whether to do just struts all around + 2 (much needed) mounts for the rear, or getting the Quick strut package all-around. Price for my car ('93 Altima) would be $370 for quick struts all around or $150 for 4 struts/rear mounts and hope I don't find anything else that needs to be replaced. I've only read one bad story about the quick struts and that was on a car with a bad design from the factory AFAIK. I need rear mounts for sure, the springs & boots appear good w/ the car still on the ground, but haven't taken the assemblies out yet. BTW, these prices are @ Rockauto + Monroe's rebate that's going on until the 31st, so I need to make a move by then. Thanks!
