Laysons for an arm and leg, or try that northern auto (a little help here?) place that buys/has loads of NOS parts. I think they are in Austin, TX? Im going to try and cast my own from some crazed originals. Should be a fun project.
I sold my set of nice reproduction items about 6 weeks ago for about half what "Vendor 'L'" gets. I will likely have more of them to sell, but not sure exactly when so can't help you right now :-(
