Canadian Members - Need clutch installed in Alberta for Maggie CTS-V

I am in Edmonton. Twin disc is pooched. Need a decent clutch for 480RWHP and street tires. Any recommendations on supplier and/or installer?

I have heard good things about the LS7 clutch but I can't see paying more than aftermarket for similar durability. Thanks for any responses.

Edit: Is it still worth ordering from the States or have parts prices in Canada come down at all?

If your in Edmonton I would contact Horsepower Solutions, I bet they can recommend and install a clutch for you.
