Ok, I did some research on this today. After talking with jbhill on the Ranger boards, the upper control arms will indeed bolt on. He has done this with his newer Edge, in which he installed the 98+ Ranger arms and flipped the t-bars. He says it's corrected the camber issue, but I'm not completely sold on the issue. After looking at the pictures on the control arm, it doesn't look all that much longer than our current stock arm. But, it works.
I would love to get a set of these upper control arms, flip the adjusters, replace my 2 inch blocks with 3 inch blocks, and be set. But, I want to make sure I can get it aligned good enough.
