    If you are using studs that are threaded into the axle flange the right drill to tap 1/2 - 20 thread is a 29/64ths. If you are using a 1/2 knurled stud and want to do a pressfit you had best get the studs first as the knurls are all different, i'd do a 3-4thousands interance fit but on a test piece, you want to press the stud in ( 3-4thou might be a bit on the 'soft' side, need to test one first, so buy an extra one or two for throw aways)

    What do you not understand about OJ's answer? That's as clear as it can get.

    I have to agree with OJ and ALCHEMY. This is a RELATIVELY simple process with regards to the LOGISTICS of the project, but not a subject to be taken lightly. Re-drilling '40 hubs can go "sour" really quickly if ya don't have your ducks in a row. There's a whole lot more going-on here than just drillin' five new holes the "correct" diameter. OJ answered your DIRECT question pretty much spot-on. It seems like there are a whole lot of directly-related questions that you have failed to ask that NEED to be taken into consideration before you start a project like this. Ya don't just "knock the old studs out" and then get the drill out for the new holes on a deal like this, especially with OLD FORD swedged studs. Be careful...do more homework. DD
