There is a slightly differs shape on the the later >08 side panel and the earlier ones. I can check if they are interchangable later today. BTW, there is a year listed on the sticker so a close inspection could reveal it as being different. No chance of the 7500 mile exemption since you've already been to DMV and it is in the system. Technically you still need the fed sticker anyways. I think you'll get this registered, no need to sell or part out. It's just going to take a bit of time and effort on your part. I would even volunteer to swap gas tanks from my 05 with you if it comes to it. Need to be sure my sticker is legible though.
