Would anyone happen to have a 13B front cover they would be willing to part with.  I'm installing one of Richard Sohn's adapters on my 3-rotor but prefer the 13b oil injection pump for simplicity.  The aggravating thing is that I know that I have one around somewhere, but for the life of me, I can't find it.  I'm sure nobody else on the list has ever had that problem.
