I have a fix......at least it worked on a 68 big block 'Cuda with RMS front end.
HDK upper shock mount and support hoops were utilized along with shortening / cutting 1" out all four control arms. Also was able to go to a 12" spring / shock combo which (IMO) smooths out the ride.
not a bad idea and a good suggestion (agree about the 12 inch spring) but man, i can't imagine cutting up a 5,000 dollar suspension and rewelding it. I'm sure it'd work just fine but dang that's a lot of money to cut.
