Does anyone have a basket or rack mounted on the rear deck of their 570?

I want something like the Mighty Light Rear Rack. Don’t want to have to butcher the back deck but am willing to make minor mods. I haven’t found anything that will fit the 570. It would be nice if I could adapt something to the lock & ride holes. Anyone have ideas or experience custom fitting a rear basket or rack to the back deck?

thanks
