Rodney, just in case you're still monitoring this thread, a couple of questions regarding air chisel use to remove the bushings:
1) On the uppers, is there any worry of dinging up the lip that protrudes from the arm's body? Just make sure the chisel is hitting the bushing flange, not the lip? Does the chisel need to be dull so it acts more like a hammer than a chisel?
2) On the lowers, how do you get the chisel started, since the flange of the bushing is flush with the arm? Again, I'm worried about dinging up the arm....
Thanks,
Dave
