Some years ago I got an original out of the Roush 'stash'. And since Jim Dove got almost all the patterns and molds from Ford when they closed out the FE after '76, I believe he has the ability to make such things.
They're an interesting design; using a regular-type geroter pump in the factory location for pressure and a pair of all-gear pumps in pockets in the pan casting for scavenging. It's of note that for a long time since, all the pump stages have been hung on the outside, but now such outfits as Dailey are once more incorporating them into a (billet) pan.
