O-ring for 575sci

Guys I am putting together my list of gaskets I need for my supercharger swap in the spring (575sci stock blower to TBS 575 replacement) but noticed that the supercharger oring is no longer made. 25-844473. Ebay has it for $60 which seems extreme. Anybody have another source ?

I ended up picking this up for $17 figured it was worth checking out for the price. Turns out it is what I needed, leave it to mercury to mark parts WAY up!
