Uk RHD Boxster S, heater core swap

[DavidC_UK]

Morning.

I'm trying to change my heater core but have hit an issue.

I'm at the stage where all I should need to do is remove the old core and fit the new one, but there's a solid AC pipe blocking the core from being lifted out.

Has anyone else tackled this problem and won?

All they youtube videos for this appear to be LHD models where the pipe runs below the heater pipes, not above them.
