i bought a kit used, and received 4 sleeves, 4 springs, 4 perches and 4 rubber top pieces. however i only received 2 metal pieces that go inside the rubber pieces. am i missing 2? or where they not suppose to even come with it? here is what im talking about.

 

Those are the OEM dust covers that have been cut down. When I took my GC/OEM shocks apart, I found the shop had only left those in the rear.

If this kit is for OEM style shocks, you should have also recieved 4 black polyurethane sleeves that go between the red aluminum sleevs & the shock bodies. If the kit is for Koni shocks, I don't think those black sleeves come with it...
