Where can I get aluminum valve covers with "Oldsmobile" on them in script lettering for a 350 engine? How much

I cant find them anywhere with the old school "Oldsmobile" writing on them. I could spend $150 or maybe a little more.|||did ya check out "e-bay" ???|||You don't mention the year or the type of script. These are steel, but can be chromed if you want them shiny.
