I just got the car a little while ago, no hatch lock at all, got a donor car with a power hatch setup (dont need the power thing and i dont think it works anyway)

Anyways I need to figure out how far down I need to drill the holes from the lock assy into the lock spacer so it lines up at the right level with the hatch (so it closes right, doesnt leak etc...)

thanks, if this is a dumb question sorry guys
