Another bullet dodged! That could have been very messy.
Do you know what the braced arm came from? Did you add the brace? It begs the question; was the brace anything to do with the extra stress at the pivot? Probably not. Those housings are properly cracked and yet appear beefier than standard. Could it be a well raced 851/888 arm? I wouldn't bother with the bracing if it were mine, just extra unsprung weight for un-required stiffening on a road bike. Your spare arm looks as if it may have come from an M900Sie, it has two holes on the rear brace which would mount the extra little mudguard piece of an Sie. But for all I know they probably all have those holes? Your brake torque arm bracket is on upside down btw.

It only fits that way due to the counterbores, bear in mind it's not a Ducati part rather an Aella aftermarket so maybe a slightly different design?

It looks as heavy, if not heavier than a standard steel one and renders the brake virtually rigid with that geometry. Bitza made one from a bit of 1/4" Dural I sent him, along with a pattern. The rose joint will go either side, so that's not important.

I had made something similar for the old swingarm but as it attached to the brace, it didn't fit this one so I bought the Sie part. Keeps the exhaust from getting shotblasted...

Looks a nice bike, glad you've got it all sorted...as others have said, I don't think there's a need for a braced swingarm on a road bike.
