Front Drum 71 Scamp

First you'll need to figure out if you will be preserving the LH thread on the driver's side hubs. The studs and lugs are available through Dorman products. Most parts shops have a bin of their stuff in the back, but since they get to choose what the stock, they may not have the LH supplies. I've been lucky up to this point. If you can find the Dorman numbers, you should be able to get through Rock Auto or Summit if the big box parts stores aren't available.

I don't recommend banging the drum in a parking lot. My concerns are possible mutilation of the drum (I can't guarantee a flat hit) or the bearings and races. As Cosworth suggested, banging the drum around in the parking lot is not fun unless you like dealing with Rent-a-cops or your local constabulary. (Make sure you have no outstanding warrants. If you decide to do the parking lot bang, your session could be interrupted indefinitely.) Grinding down the swedge with a Dremel tool seems a reasonable way to proceed.

When I have done this, I've had access to a press. When removing the stud, I made sure the hub was level and pressed with a disposable nut on top of the stud and supported the hub with a socket large enough to let the stud fall into it. To install the new stud, I put the large socket on top and pressed directly on the stud at the bottom. I did this one stud at a time. My goals were to minimize "wallowing out" the holes in the brake drum and to maintain a good concentric run between the hub and the edge of the drum. This worked for me.
