I thought it wouldn't matter, as the cars are the same year, and I thought the GPs and Imps were made in the same factory. But I noticed a stick on the GP that it was made in Missouri, and I know the Imps are made in Canada. I've seen them on eBay, so I'll give it a shot. Worst case, I put them back up on eBay and lose a couple bucks for a lesson learned.
