Mount Stuart, 1986 Girth Pillar Left (AKA Girth Pillar East) route location?

[Michael Telstad]

Does anyone know where the 1986 5.9 A2 Mark Bebie, Charlie Hampson route up the left side of Girth Pillar goes? I've a attached a photo from @Kyle M with where I think the line roughly goes, can anyone confirm this? 

There's a steeper corner on the pillar proper that seems more fitting to the grade than the line I drew.
