concentric part number and bump stop cap part number
 

Hi there,
I damaged one of my contentrics on one of the rear lowering control arms when installing shocks, does anyone know the part number for this so i can call mazda and order it?

Also,
i over-drilled the bump stop caps when installing shocks, and had to use washers to make it work. I don't like this setup. Does anyone know the part numbers for the front bump stop caps?

thanks for the help
Jordan
