im not sure whether or not you have the supercharged version or not, but it listed the same part for both engines.
heres a dorman part #34196
and i didnt see any listed on ebay, but heres a place
idk what shipping would be to canada, but any local parts store should be able to get that part. but considering how expensive canadian parts stores can be, it may be cheaper to order.
**edit- and looking at this belt routing, i dont think its possible to re-route it, and avoid the w/p nor the mount you mentioned.
