Is the TRX300ex on the same frame as the TRX250ex?

I found the rack I want but it’s not made for the 300ex but is for the 250ex…

This is the rack

I emailed Moose Racing and got a quick but ambiguos response. They said they didn’t know if it would fit the 300. I responded that I would be more than happy to be their test monkey if they would allow me to retrun it if there was a fit issue. They said they could not.

Any help or similar racks that you know of that I did not find is greatly appreciated.
