out of commission, cant drive my dart anymore

Just about done but have yet another problem..I have 3 lug studs that need replaced. 2 dont even look bad so i went to harbor freight to buy the 40$ tap and die set, but it sucks! The die reuses to start straight onto the stud, then theres the problem of the die holder hitting the stub sticking out of the center of the rotor, so i tried to grab the die with pliers to thread the stud and it broke in half! So im done with that, i will just take it back apart and beat the 3 studs out and put in new ones. Anyone know a source for these K-H studs? I THOUGHT i read something that Hemi71 said about them being hard to find?
