Lower Control Arm bushing dimensions! Help!

Im gonna send the lower arm to a machining shop so that they can use the press to push the bushings out. But i need to clarify 1 thing 1st:

Do i ask them to take out number 1 and leave number 2 as is, and put the new bushing inside number 2, or...

take number 1 AND number 2 out and put the new bushings in there?

I hope you get what im trying to ask. :)
