Hunting for a small-journal main cap...

Where does a guy find one? I'm looking for a 2.299" cap. Casting number 3951. It's actually for a 181 Pontiac/mercruiser, but as far as I can tell, the 194, 230, 250, and 292 inline sizes, and at least some of the 302's had them as well, maybe more.

Is there anything I need to know other than the bore diameter on these things? ...also, anybody have one they'd part with?

Thanks a ton!
