I've never had a t8 because I live in the UK and no one deals with them here. I would love to have one tho !!
But in a previous post on here about the t8 they said there is a slight groove that the divider goes in and the divider is screwed in so you'd have to keep making holes if that's the case.
Although now that I think about it that might have been a different make not an AP cages.
