73 and later have the stabilizer bar routed theough the middle of the K member. No caliper conflict there. Pre 73 have a stabilizer bar that routes around the front of the K member (low hanging triangular forward mounts too). 73 and later spindles and calipers at forward position with that pre 73 design doesn't work. Calipers collide with the stabilizer bar. The common solution for many years was switch the late model spindles left to right so calipers move rearward. Bleeders needed to stay at the top and longer fluid lines were required. In recent times a few owners, with forward thinking minds, have found that the calipers could stay in the forward position if the bar was loaded below the pre 73 end link tabs with the later model end link kits which are much shorter than the pre 73 end link. Only issue is the end link kit is just a small bolt though some bushings. It's pretty easily bent if off roading or in a collision. But... like I stated above, the early bar had lower hanging triangular forward mounts too. We've seen a lot of those with broken bolt ears. I think the concrete bumpers in parking lots prompted the change/re-engineering of stabilizer bar routing and location of forward mounts in these Chryslers.
