I found it on a sticker on the frame under the seat. It says it is a TRX680FGA8. I never thought to check my registration earlier, but is shows TRX680FG8 which is what comes up through the VIN number and that is not the same either and that number doesn't come up on website which has after market bumper. Their options are TRX680FGA or TRX680FA. The first model number is as close as it gets, but the picture of the bumper shows it bolts to the front rack but the front rack on my machine doesn't have bolt tabs it has tubes going down behind plastic that are welded to the rack itself. Not sure if it is a generic picture on the website, so I will call them to verify.
