The kit will include all the items needed for installation. You will reuse your bolts to connect the arms to the chassis.
These are "Press In" inserts (but a large vice does work). These use FK bearings (very high quality, same ones in Wilhelm's kit also). Each bushing is made from 6061-T6, hardcoat anodized. The bearing inserts are made from SS304 and then passivated.

I wrote an article about the spherical bearings and how it compares to poly bushings.
