I have a 904 Drivers Manual (Rough Cond.) and a "Porsche Carrera Guide" (1500GS,1600GS,2000GS) ..... Neither is in Great Condition , but i assume they are worth something to someone . I am not a 356 guy ! ..... I am Barely a SWB guy . If you can advise me on other sales of these type of Bits .... please give me some Direction . Todd
