I am trying to fit a genuine Ford dog guard to my 2003 53 plate Galaxy. It needs the upper seat belt anchors on the C pillar to be replaced with a longer bolt, but I am baffled by the type of fixing used on the old bolt I need to remove. It isn't a TX5, or TX5.5, but is somewhere between the two with what looks like 12 points to the 6 on a TX fixing. Can anyone help with a name for this type of fastening? Thanks in anticipation.
