Replying to Adjustability of PX12 bindings

Hey, my buddy has some skis that Im going to borrow on Sunday (OG blends with px12's)

His BSL is 317 (28.5) and my BSL is 342 (I know, my feet are way too big for my own good), will this work? I know they adjust a few sizes, but I guess what I'm trying to ask is exactly how far they go, I wanna hear numbers, so dont bother responding if you are going to say "it goes a couple sizes. I've gone from a size 29 boot to my boot with px12's before, but Im not sure of the BSL. Thanks for reading my shitty thread.
