Dan, you may be right! Now that I see that, I think it very well could've been Quadra-Trac that I had in mine. Either way, when I replaced mine, I found it at a local 4WD shop. They had a few of them lying around from Atlas swaps they had done in a few ZJs in my area. I picked it up for $300.00, but in retrospect, I wish I would have just done the 242 swap, instead of replacing the 249.
