hey guys, okay, trying to put a leveling kit (new torsion keys) on my 99 silverado. but after ten years of driving the bars look to be rusted into the keys. worked on them for many many hours today, trying to get them free so i can slide them forward. but they just really do not want to cooperate with me. i already have the tension off the key and the bolt and holding nut out of the way. i have tried everything in my knowledge to get it, but i need any tips on what i should do. thanks for any suggestions.
