Need help identifying crossmember
 

I bought a roller that came with the cross member below. Can anyone identify it? I havent found an exact match on Google yet. I'm wanting to say it's a TH400 conversion cross member but I can't say for sure. I would like to sell it but I want to be able to tell the buyer whether or not it will work for them! Thanks in advance guys!
