Hmmm, so I'm going to want to keep the canister then to facilitate that? I'll have to hide it somewhere then, hah. Trying to get as much out of the bay as possible.
Drilling the welds out might not be a bad idea, I will already have to in order to cut a hole for the intercooler piping. I'll check tomorrow to see exactly where the welds are.
I tried a breaker bar on the mounts but you can't get it in there quite straight so it doesn't work. The bolts area kind of inset within that brace.
EDIT: Just found my answer pertaining to that vacuum line thanks to Russ. The answer is here for reference later if anyone needs it:
