Condolences to you.
And may the perp have acid reflux for five years straight.
No idea about other aspects of parts or repair needed, but I can assure you from recent personal experience that rear brakes are expensive. Without walking down to the Moto Grappa to see box and paperwork, I think it was c.$450 plus shipping.
I have a new, never-mounted one I bought last year, then decided I didn't need. Long story; won't tell here unless someone is bored feceless!
I was going to put on the mercato, but your need is likely more immediate. Email -- not PM -- me if interested. Substantial discount as it'll do us both a favor.
Will be in Kentucky twice this month, first on V7 III and then on GRiSO, so can probably even do a hand-off somewhere near, thus saving shipping.
Again, sorry for the damage. I detest such low-lifes.
Bill
