Gerahead's 71 Dart

After a way-to-long delay, I am back working on what a good friend of mine calls a "staic display". Lots of work related travel and a herniated lumbar disc can keep even the best intentions subdued. I have had that corrected and am just waiting to get the post-op okey dokey from my doc, so I can resume my "normal" activities. Quite a while back, I had posted a question looking for help . . . .
[When I disassembled the car, I removed the K-member and entire front suspension intact including the front tires. As you can probably imagine, it has been quite a PITA to shuffle it around the garage as needed to get at other things. The other day I took advantage of HF having moving dollies on sale, so I got one to place under the assembly so that I can at least roll it around when I have to move it. One of the reasons the tires are still on it is because a previous owner installed Gorilla lock nuts on virtually every wheel stud on the car. What kind of idiot does this ****!!! The only 'key' for these locking lug nuts is one that I found loose in the trunk eons ago. Those of you out there who are reading ahead . . . . . you are absolutely correct, the 'key' did not fit on any of the locking nuts :wack:

What I had found on the rear axle is that I could drive an undersized impact socket over the nut and tightly wedge it over the largest OD of the nut and then use my impact wrench to back the nuts off. As is always the case in things like this, 4/5 came off relatively easily. The last one is just a *****. I finally gave up when it got to the point that I was getting so angry, I was going to hurt something. Put everything down, go inside, mix an adult beverage, calm down . . . . . solve this one another day.]

I thought that I had a plan, I would grind the end of the lug nut flat and weld a 3/4" nut onto the end and just spin 'er off! All I managed to accomplish is destroying two 3/4 nuts because the welds just tore apart. The wheels are the old Fenton style slotted mags and even though I am not going to use them on the car, I didn't want to do any damage to them either if possible. If it wasn't for that, I would have already broken out the gas ax! I am at my wits end. Does anyone have ANY idea that I could try to get this one last lug nut off?? I am at the point of desperation! Thanks, guys. L8r
