A518 46RH rebuild

Well, it looks clean, but I didn’t bother measuring clearances because when I ordered it, I knew it was a flats pump and I have a brand new lug drive converter and I thought I could just put my pump parts into the new housing. The flats drive pump is a larger diameter so my parts leave too much of a gap so I’m back to looking for parts.
Either a larger diameter lug drive if there is such such a thing, or I see how much of a loss I take on returning the converter and getting a flats drive one. I’ve had it for about eight months, so I’m not sure what they’ll do for me. I have some other things too take care of today, but I really don’t want to push it into yet another week.
Just curious - what'd they charge for the pump assembly?
