Yup, I did mine in 2006 with a '75 clip. Luckily, I had been questioned before, so I captured the whole process by taking pictures. Peg took it and created the Tech Tip.
If you look at my Suburban, my front springs are a little saggy. If I had fresh springs, putting my Suburban at stock height like Terry's, I'd have zero rubbing issues. And, to tell the truth, a lot of my rubbing issues went away when I installed the rear sway bar. In fact, the ride improved vastly!
Sometimes this stuff has to take a little adjustment. Afterall, the clip was made for a passenger car/Camaro and not a truck. Certainly not a Suburban.
