Ryan, you already have all the unique "chrome" trim (anodized aluminum really) so you are in very good shape. Only the rear bumper is an issue. There was a time when bumper shops were common and chrome was affordable (prior to the clean laws in the early 1990s). You can see about getting that rear bumper straightend & properly rechromed (cheaping out in that area will give poor results that don't last) or you can see about finding a straight replacement (not a common thing to find today, given the Beaumont backup light provisions). Overall you have a great car there. The easily fixed stuff, like the common lower fender & trunk panel rust are not going to be a problem, since the trunk floors have been reproduced for many years as they were a prone area and common stamping to many cars. If you are new to this, try to document and photograph  as much of the original stuff as you can, since they will become important reference as you get deeper into this project. The Canadian cars were finished differently than the U.S. Chevelles, with body-coloured firewalls & trunks, plus the floors. One day when you really become an expert on these cars, the shots from your unmolested example will become a lot more important than they7 may seem right now. I see you have the unique Canadian air cleaner. Do you still have the valve covers? Even they are different than the U.S. parts because the U.S. parts are stamped with a "Chevrolet" script. I you decide that you want to modify the car, at least try to group and keep the original parts. One day, even if you do not use them yourself, some Canadain Poncho fan will be glad you took the time to care for the unique Canadian parts. Keep us posted on your progress, even if it is a lot slower than you care to admit. Many of us have been there...

BTW, welcome! You  are in a good and safe place.
