Jeep 4.0 in 69 Barracuda

Pretty interested to know how that AJE rack conversion K member goes...there were some less than happy customers I found elsewhere on the web...according to one guy in particular, the control arms would bind on extension, ackermann angles were off, bump steer sucked, and the rack needed relocation. I still have my heart set on the HDK kit, but options are good to see. Unless I'm looking at the kit incorrectly, it looks like the rack is located on the aft side of the K member so you can keep the factory style spindles...or am I looking at this thing bassackwards?
