Dan, I have questioned this some in my mind, but I have no answers, just a couple of thoughts that may lead to answers. The Caprice/Impala had 12" rotors on the wagons & have the same wheel bolt pattern as the trucks. I had planned to check this out at one point, but never did. I'm wondering if the ball joints, tie rod taper, ect have something in common (my guess is yes, the G-body guys are able to swap this on for bigger brakes & the wagon's rear is more like the truck, brake wise, so I'm thinking maybe the front is also) & if the knuckle height is doable. That would be my first thought, get with a buddy at the local parts store & see what interchanges. Beyond that, I'm sure there are some high dollar kits out there. Did you change to a Ford bolt pattern in the rear? Good Luck & Post your findings, Lorne
