I just did this to my blazer. Dropped the gas tank, used a grinder on the rivets then beat on the stock hangers until they came off. Then I had to grind the rivets even with the frame and beat them out with a punch. I did the drill bit trick with the first spring bushings took forever big mess still had to drive the bushing out with a BFH and a punch. I had better luck on the second. I took a sawsall and cut the bushing and then drove them out with a BFH and a punch. Make sure you are hitting the metal sleave for the bushing with the punch. I also used lots of WD40.
