the first pic is of the stock shackle. notice that both bolts are on the frame side. this caused a bunch of clearance issues because there wasnt enough room for the bolt to slide out. the first thing i did was to take off my trailer hitch and spare tire (i ruined 3 3/4" sockets in the process of taking the hitch off.). use a torch! if you think they are hot enough..... keep heating it longer. it really helped. after that, i heated the shackle bolts until glowing hot and the bottom bushing was catching fire and smoking.put a 7/8 socket with a breaker bar on the bolt side and a wrench on the other. GIVE HER HELL! its not going to be easy expecially if they have been on there 15 years. but dont give up they will come off. you may have to use pb blast(it couldnt hurt). after i got the nuts off i realized that the bottom bushing was seized to the bolt. i heated the bolt up again and put vice gripes on the bolt head turning it and beat the crap out of the other side with a hammer. i kept doing this until finally it broke loose and came out. the next step was to lift the rear end with my floor jack util the top bolt cleared the fram inbetween the bed. they came right out. sorry about the second pic by the time i installed the new 2" drop shackles i was beat down and didnt care how the pic came out(will take another). it was alot of work for 2"(thats what my wife says too!hehe)but i am happy with the first step in lowering my truck.
