There is a pair on Aussie eBay that need a chrome strip and re-paint. The seller does not realize they are RIVCO risers.
I could use the top clamp in the years ahead to fit a 2" set of Stainless Burleigh Roller bars that need the 10mm riser mounting holes drilled to 1/2 inch and just send you the risers.
Air Post to USA for the risers would be about Au$45
