I am in the process of installing a 6" lift kit on my 99 chevy k1500 LS. I am having difficulty removing the passenger side bolts that hold the shock absorber in place. I really don't want to take it to a shop, as I have removed all the steering knuckles and such. I have tried heat as well as soaking it for weeks with penetrate. I use a 1/2" impact gun for all my projects fyi. Any suggestion?
