I have read that the banana can turn on the axle if not welded to the tube. Definately not hard to do and may come sooner than later but I was curious as to what you all thought.

It has an arm that comes off the banana and goes under the 8.8 and gets bolted to the diff. Is this a new part that was added to later 3 link kits? Other threads made no mention of it. Now I am wondering if i need this 3 link brace kit from here. http://www.vintageperformancemotorcars.com/

What do you all think?
