Late to this thread but did you cut your can just to be rid of the bosses the clips mount to, no issues being clipless? What length can did you start with and where did it wind up?Here's two different dil-out configurations. Mine has the pair of 3 l and one I found on Facebook from Frederic Page is the one with the aluminum 40s.
Worth noting I had a shaved cave canister and currently use a custom cut canister latches are deleted now. But I made sure I could use the rear latches on the first version without removing the 3l.
Frederic has a standard can by the looks. And the 40s look like really nice rig to use.
