Well its been at least a month since I posted the IRS control arm issues. Since then I have scoured the planet to find a set of standard width arms. Haven't had any luck, and even worse, zero help from the people that shipped the wrong ones in the first place. Now after contacting Factory Five a few times, and sending another load of money, they are digging the old jig out of storage, and are going to weld up a set for me. They said it'd be a few weeks. I really don't like the feeling of paying twice for the same item. Anyway, to everyone out there. I know where you can buy a brand new set of older style IRS pin drive control arms. I'm trying to recoup some money out of this. The original vendor won't even return my calls. So they're for sale. I'd also like to say thanks for the information everyone provided to help me figure out the problem in the first place.
