I'm probably the only one dumb enough to make these mistakes, but just in case.....
First, I learned that the axle tab holes should align plumb with the holes the in arms, regardless if the arm is level to the world (or at a ninety degree angle to the links that connect the arms to axle).
I'd planned a 90 degree arm to link orientation, but the 21" arms didn't work and had no choice on where to mount the actual bar, so they're at 125-135 degrees.
That wasn't that big of a deal, but I didn't take into consideration that the link has to be plumb, had little room to work with on the axle housing, so the first axle tab had one hole ~2" aft the axle tube.
Realized how ignorant when I wanted to increase the bar's rate and move the link closer to the bar..... and wound up having to cut the first tab off and weld new (that I bought from Currie).
Second error was ordering the links cut as if 90 degrees was going to work. They were too short, so ordered longer than needed and had a heck of a time finding an locals with a LH die to cut new threads on the odd OD link.
Personally didn't care for wheeling without any sway, so never furthered a disconnect, but (to plant a bug in much more capable craftsmans' ears) thought it'd be cool to use a locking hub on one end, eliminating cotter pins, or to copy one of the Jeep innovations and use a dual bar (one hollow for wheeling, solid in the center of) dual arm set up, where a single pin fixes both arms of one side together.
