I just ordered one from Mike's. Mine is the right side front, so the one that uses the smaller size studs. For now I just stuck a metric allen screw with the same threading in there with a couple washers under the head. It works ok.
In mine the deep threads are bad, but the first few in are ok, so I have to use a short-ish fastener. When I get the replacement stud I might JB weld it in, with some of the high temp JB Weld.
