longer wheels stud help

[lost wages]

i have a 9 inch ford rear end with moser axles under my 68, recently i put on a set of baer disc brakes and now i need longer wheel studs. Here is the problem, the studs i have now are 1/2" x20 1.5" inches long with a .530" knurl. i need the same but around a 1/2" longer, i cant find anything like this, is it possible to drill the knurled hole in the axle and pull a stud with a larger knurl into it?
