how do I remove/replace studs on 7 1/4

If the axle came out with just the C clip in the pumpkin, I would have done it; but these come out like the 8.25's and need to be pulled out.

I don't understand what you are saying. 7 1/4 axles do not have "C" clips. Just pull the drum, remove the 4 nuts that hold the bearing retainer/backing plate to the housing, and pull the axle.
