If it is on one of the 123 the Arm itself is not to hard to remove from the Block.

After that you can either try to get it out with and Ezie Out or just get another Arm from the Junk Yard.

Better chance for success with and Ezie Out seems to come from drilling the hole exactly down the center, using the right sized drill to match the right sized Ezie Out. After that it is the application of heat and something like PB Blaster.

I have always had trouble drilling the hole down the center; not to mention not always having the right sized drill that is sharp enough to go trough a hardened Bolt.

Also I do not like the spiral type Ezie Outs as they can expand the metal you are trying to get out.
