Quoted: The alternative (if you are or have access to a good welder) is to remove the rivets then weld the holes and grind the surface of the trunnions level. Use the holes on a pre-drilled flat as templates for the new rivet holes you drill into the trunnions. It takes a but more time but guarantees the best match-up between receiver and trunnion and no "egged" holes.

No, no, no, no, no.
The holes are where they are for a reason. Welding up the holes in the trunnion is not a very good idea because the new holes aren't going to be where they are supposed to be and all that welding on a trunnion can't be good. Look inside the trunnion and you will see that the holes aren't just random, but they have corresponding low spots on the inside for the rivets to "squish" into.
Get a flat with holes drilled and you will be "egging holes almost assuredly.
Get a flat with no holes and you can use any of a number of methods to accurately locate the holes.
I would suggest the flat with no holes.
