Rather bad problem actually.  Getting my engine back together in my rebuilding project, and when I tightened down the single bolt to hold the oil pump in, I broke off the flange on the pump.

Questions:  

It looks like that flange has a space between it and the block, once the pump is seated in place.  So naturally if you tighten very much you pull that flange down and crack it off the casting.   Did I miss putting in some kind of spacer, or.......?

If not, what is the torque spec, which I don't see in my many manuals?

Suggested source of a new pump?  I don't see any at Korves or Steiner...

Thanks for any help.
