I have a mid-range Hobart, oddly the weld didn't really stick to the lug nut. I'll clean it again like crazy and get a lot of weld on it. Cautiously optimistic that will do it. Or C4, looks to be a 7 or 8 pound job. Or so I've been told.
Just to vent for a second - I spend 4+ hours this week having to get cut a single motor mount off a Fiat 124 Spider where the DPO stripped the nut on the recessed stud that sits within the front subframe, so am trying hard not to touch a Dremel again for at least a couple days.
We do this for fun, right?
