    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 ?

    Well evidently snugging it down doesn't work. It closed the gap - by pulling the car down on its suspension. No good.

    I can't believe this is the wrong part ??

    Yes.

    Don't draw it up with the shock nut- that's a recipe for thread galling. Instead, jack up slightly on the axle until the pads are seated, then tighten.

    Thanks Todd. The suspension was fully loaded.

    So the suspension is at "rest" and the shock is too short?

    Something is most definitely wrong then. When I google "pn 24-001564" :

    We need a picture of what you're seeing. Have you ever replaced the leaf springs or had them out?

    Thanks to all for the replies. Unfortunately, I didn't think to take any pics when the Bilstein was installed. The bilstein measures about 1-11/32 inch shorter than the old shock that I pulled out. I did change the springs back in 1992. That's about the same time I installed the Sears gas shocks that I just pulled out. The Sears shock length was just right. The ride height of the car is right. The rear end isn't too high.

    With the old Sears shock, the upper rubber bushing on the bottom of the shock just made contact with the top of the shock mount. The Bilstein had a gap between that bushing and the mount. I was just barely able to get enough of the threaded rod through the hole to get a nut started. The new shock measures 22-7/8 in long when measured as shown.
