Same with the second dungeon that has level 73 dungeon gear but an ilvl matching unaugmented Scaevan gear.

So long as the actual level of your gear is higher than or matches the actual level of the gear you're trying to glam it doesn't matter what the ilvl of the gear is.

Source: Spent multiple hours trying to figure out why I couldn't glam level 63 Shisui legs over my level 60 Shire legs, realized why and facepalmed myself.
Even better info ty.....and what a weird system, i to have been doing my head in, especially after buying expensive items on the MB to find they wont glam
