Short version - where do I get the O ring for the oil pickup tube?

Hi All!  I have a thread going about low oil pressure but have a 1-off question which seemed more appropriate for a new thread.  I have dug my way to the oil pickup tube and will eventually be putting it back together but I seem to be missing the O ring that goes between the pickup tube and the block right by the oil pump. 

I searched Rock Auto but couldn't find anything (wasn't really sure what to look for).  I found a thread from 2012 saying that I can just use a generic O Ring that's the same size (as long as it's rated for high temp and oil) but I don't know what size that is since I don't have the old O Ring.  That thread also mentions buying a set of gaskets from Rock Auto but I'm not sure which set and they never came back to say it had the right one...  http://forums.cadillaclasalleclub.org/index.php?topic=122214.0

Thanks!  I would have bought the whole set but already have the oil pan gasket.

Maybe this is what I need?

My guess is that one would be wrong since it says its 472-500.   When the 500 came out in 70 that was the start of the slightly different block which casting number ends in 5200 like Greg mentioned.   One of the slight changes was the size of the oil pickup and passages.    Looking at a few other items they have listed there I see the same lack of clarity if its for the 472 or the 472/500.   Seems kinda strange that a shop claiming to be a specialist would miss a detail like that.
