Canadian source for rebuild and resto parts?

Good day all. I'm usually located a few hours west of Ottawa, in an area that absolutely sucks for internet service. On Sattelite internet, which on a good day is about as fast as dial up, maybe. On most days I may as well use smoke signals.

I'm building a 72 Dart, not a concours resto, just a summer toy. My question is, can any of the Canadian members on here point me in the right direction for aftermarket/replacement parts?

I'd like to draw on the collective knowledge of those who've done this before and save myself one day throwing my computer through a window in frustration...

So, it would be awesome to get some recommendations on where to buy or the best places online to source the following parts....

Interior parts (seat covers door panels etc)
Mouldings and trim (windows, windshield)
Brakes (want to do a disc conversion)
Suspension components (will be upgrading the suspension to tubular)

Also, I am looking for a complete 70-72 Dart parts car, body condition irrelevant, as long as it's a roller I'm interested as I have a car hauler and will travel :)

Thanks all!
