Spanish series 2 tool box lock problem

hi all im looking to resolve an issue on my Spanish series 2 toolbox lock,
will a series 1 lock without the handle fit or are the holes spaced differently , I ask because the series 2 lock fitted affects the ability to lift the seat fully when trying to fill up the seat touches the handle and restricts access to fill up.?
T.I.A
