Thanks for the quick reply and links...
I have looked around online and the only place I seem to find a refrence to it is eBay..

Although, I got the case gasket at napa for $25 and I can't see spending the extra $ for that seal (and another case gasket)...
I would expect to pay something around $5 - $10 (as like in your refrenced links)...
Any info helps...
Thanks again...
