Ok I'm assembleing my rear struts today, and with my kit came two rubber bushings (for the cap that goes on top of the spring), per strut. On the rear, when i finally got it out (fu*k seized bolts), I took the cap off and there was only one. Is there only the top bushing on the rears or should i put both on (top and bottom)?

 

there are 2 top bushings, one you can see from the top of the hat (#18), the other is underneath the hat (#16)
