I got a new pair of Riedell 195 redlines and mounted my Arius plates to them. This was a beautiful decision.
There wasn't much space on the boot for the plates, so I pretty much just centered them and tried to avoid the stitching.
I chose to use the same holes that had been used to mount to the Bont boots and traced them.
I first drilled a pilot hole with a smaller drill bit.
Second pass was with a bit close to the size of the screw's core.
After that, I just screwed them in. I had to get some odd tee nuts to put inside the boot because I couldn't find any bolts with a flat enough head.
All in all, I'm happy with my work. I love my riedells.
