Larry, I just removed my ball studs this past week, (1950, 3100). I found after grinding off the peened/swagged area on the back and drilling a 3/8" hole about 1/4" deep I had trouble. I used a big, heavy hammer and then a 5 ton ratcheting press to no avail. Maybe I should have used a larger drill bit? Anyway, I called a local auto machine shop and they quoted $65.00/hr and 1 to 2 hrs work depending on how hard they were stuck. I asked him how big his press was and he said 20 ton. Heck, I ran out and used my $149.00 Harbor freight coupon to buy a 20 ton press. About 1/2 hour and they all came out nice and easy. So my press is half paid for!
Now if I can just find a way to use my Napa ball ends, (tapered shank), to fit my Pitman and steering arm, (the new modern tie rod ends that are available go right on in the straight holes), I'll be all set!
Good luck,
Tim
