Best way to geometric tolerance this part

I'm not very good with geometric tolerancing and I waswondering what the best way is to geometric tolerance this part.I'm trying to keep the thru holes on both parts from shifting offposition by .005". I'm using the boss and pocket on the parts foralignment. So I guess the boss and pocket will drive the locationof the thru holes. A collet will be going through the holes and Idont want the collet to touch the holes.

Thanks,
