Hi im Carl Cordova and im new here. i have a 1999 Tahoe 4 door 2 wheel drive 5.7 vortex. i use my truck to do a good amount of towing, my question is "could i take my truck to a machine shop and Safely take out the rivets and do a reverse shackle?" to lift the rear so the truck doesn't squat so much. any advice would be nice thank you.
