A-body frame to body bushings come with factory correct 7/16 flange head bolt with chisel point.
 
Bushing kit comes with Oldsmobile correct amount of 8 bolt on bushings and 4 bushing rubber pucks. The pucks will go over the rear and commly in the middle of the frame; although we have seen them elsewhere on the frame. The body mounts that are not used will typically have chaulk in the threads.
