So now that I have dual discs on my 756, what are my options for my 857?

It'll be some time before I actually upgrade anything on my 857 frames, but in the interest of having options when I get around to wanting them, what would it take to put rear disc tabs on an 857? It doesn't seem like it would be an ideal candidate for welding, because of the glue holding the lugs onto the carbon fiber arms, so...would I need a bracket then? How have other people done this upgrade?

yes I had this on mine (it came with it when I bought it 2nd hand). It used the 2 holes that are already in the end of the swingarm.

I believe that's an RDS disc adaptor.  Unfortunately I can't buy one anymore.
