I have an extra set of used rear shock mounts.  I had to cut mine off when I re-did the rear spring a few years ago and then I somehow ended up with two sets afterward.  I think I bought one set from a local guy and another on e-bay.  Anyway, how about $20 (OBO) + shipping?  Paypal is preferred for payment. No other hardware is included than what you see in the pic.  Dave
