I am replacing the shocks on my '79 Camaro with Bilsteins. Fronts fit just right. The rears (pn 24-001564) seem to be too short. I have top bolted in. There is a gap (about 1/4 - 1/2 in) between the rubber bushing at the bottom and the top of the mounting pad. Do I just use the lower nut to "pull" it down ?
