Bolts: GM part 11518445 - Says for the rear not sure if for the front as well??
Striker Cover from Cadi: 13574802 Not sure if will fit Caprice
New Striker: I ordered some new ones and they did not come with a rubber (black) section on the catch.. THink they discontinued those. Ones I got were all metal.
