Gearwrench makes an adjustable pivoting head wrench that is quite similar in design to the custom fab job. I love the ingenuity generated by necessity.
The wrenches this guy makes are bent to get in behind the alternator.
He said that Fab Job #1 would not work, it got into a bind.
My set was Job #3 and he remade mine a bit different than his.
I "just happened" onto him talking on a forum, and wrote to him and asked "will you make me a set?"
he did, and told me that it is okay to tell others about it.
