I'm loathe to trash OEM parts, but that said, it does seem like these parts are truly unwanted. Except where indicated, all of these parts only cost the price of shipping via USPS, plus a cheap beer. Everything is in good, or even new condition.
OEM oil cooler, lines, fittings, good condition
OEM airbox, good condition
NOS OEM clutch cover gasket
After market bar-ends, great condition (note: these are not the RPM bar-ends, they are a different manufacturer and were previously installed on my '89)
OEM mirror, left, good condition - $40+shipping, OBO
