I am going the same direction you are with the Alter-k-tion front end for a number of reasons especially with improved geometry but also more stock tire choices. I have two questions. Does the suspension in the front have anyway of tying into the shock tower for added supporting of the weight? I have heard from others that there is too much stress on the upper spring support for a Crate Hemi. The second question is about the Street-Lynx and location of the angled link tabs to be welded to the differential. How are these located and does the u-bolted shock mounts on the rear end index off of the old spring perch on the differential?
