Rear Hanger for Wilier

I am having great issues identifying the an aftermarket Wilier hanger for my 2011/2012 Wilier La Tristina.

I have had 2 rear hangers snap in less than 300 miles and I was wanting a more substancial version than the Wilier original. Now before people say there is an underlying issue, I am aware of this and the bike is in the shop having it investigated but as a failsafe I wanted an aftermarket version as I beleive these are 'beefier'

Any help would be much appriciated.

Cheers
