Minor update....
EASY SHACKLE REMOVAL
I started disassembly of the front suspension last night. All bolts came off fairly easy, so I took the opportunity to do some degreasing, clean-up, spot rust treatment, and painting all the parts I can't get to when the wheels are on. Like so many others, I got stuck on trying to pull the old shackles out. I screwed around with the first one for over an hour with hammers, pickle forks, and a pry bar to only get the first one out about half an inch. I finally gave up around midnight. While I was taking a shower before crawling into bed, it hit me..."just drill them out". I busted out of the office during lunch to come home and test my idea. Worked like a charm. I had the front PS shackle out in about a minute and a half! I'm sure this idea isn't new, but haven't run across it yet. He's what I did.
Removed bolts and shackle side plate. Chucked up (5/16th I think) drill bit and drilled into the old bushing. Drilled a couple holes around the bushing and hogged out material until the pin was loose enough to tap out easily. Chucked up a 1 1/8" spade bit and ran it inside the remainder of the old bushing. With the pin out and the spade reducing the amount of inner material, the old bushing popped right out after a couple seconds.
I'll get some pictures on the next one.
