Your clests were probably not factory installed, just screwed in.
Factory were bolted inside the transom thru the inner liner. Accessed thru a inspection port.
Docking Lines were fed thru the hawse pipe. If you going to keep them on place, you will need to drill thru the cap and bolt them yourself.
