The Mk3.5 isn't a Mk4 or Mk 4 facelift though Thrush you numpty

Both the Mk3 and the Mk3.5 the screens are held in with rubbr seals. The visual differences are the use of a fuel flap as opposed to a cap and the mirrors look the same as those on the Mk4. Seem to remember the boot lid swage lines aren't there on the 3.5 either but could have imagined that.
