As you may know up in Canada the Pontiacs were built on Impala chassis for 69 and Chevy-style rally wheels were an option.

I read on one site that to get the "wide track" for Canada, they used a US Chevy Wagon rally wheel which was supposedly offset more. That doesn't make a lot of sense to me.

So my actual question is whether there really is any difference in a "Wagon" rally wheel. So far as I can tell for 69 all "Passenger" rally wheels are coded DC and there's no special rally wheel for wagons, but I'm no expert.
