I have a bunch of New Old Stock Sun tachometers, housings, and a EB-9A Transmitter for 8 cylinder, 12 volt applications. All parts are listed individually on Ebay with a $9.99 starting price and NO RESERVE. All auctions end tonight at 7PM Pacific Time. Thee prices are currently super low and there could certainly be some deals. Free shipping to paid members in the US. International buyers will get the shipping discounted by subtracting the US shipping price from the international cost.
