KW V1 fitting. New drop links? And rear dampers?

Hi there.
Have a 200 and today fitted new kW v1's. Question is, I need shorter drop links for it. Does anyone know which ones or have had experience with them? They're wayyyy too long to be honest :/
also anyone know how to fit the rear dampers. I know you need to drill a hole but it still pushes through up until the seat belt holder. Any ideas?
