Hey, I said I had an IDEA... lol
Firstly, KC has made some Expos jerseys that you would need to download.. I forget which team they are attached to. I would just take a stadium (any existing stadium that would look like maybe something the Expos would use) and put Montreal related ads, Canadian ads, etc... then rename the file to whichever team I needed to replace - I would supply a backup of the original file in the rar.
