Yes, I said this above where I posted the pics of the Nomad baffle and the Wagon baffle:
"The stock hole that the grommet goes into is 2" in diameter on a Nomad. Looks like it's smaller on a wagon for some reason, per Robert's pics. So getting one from a wagon (if that's even possible) probably doesn't help."
Thanks for looking I'm sure lots of other guys need these too, they just don't know it.
