Interior Door Lock Thread?

[MrVeteran51248]

Wife got me a set of door locks. I tried to install them but the ID of the new parts is too small. I am thinking of drilling them out and tapping some new threads into them. Anyone know the size of tap I will need? I haven't popped off the primer to see if that is where it is threaded or if it is on the brass side. Thoughts?

What I have found out, is they were designed for the Minis. When I get ready to drill them out. I will post the size bits and taps I use. I will have to see if I will need a bottoming tap though. Not 100% sure. Not my area of expertise.
