Source for Microseiki BL91-L arm board.

I own a Microseiki BL91-L TT and am looking for an arm board to accommodate a Saec tone arm The problem finding a srouce for the board and a board that has been drilled for the Saec WE308 tone arm. Any help here is appreciated..
Try 2juki you will find his ads for Micro parts on ebay. I have just ordered an arm board for my RX-5000 from him even though his website says he is out of stock of that model. there a a couple of other sellers of Micro parts there too.
Regards Steve.
