Hey!!!
I just did this the other day. You need a BIG hammer and a 5/8 chunk of barstock or a punch. Take out the keeper bolts and drive out the pins. Look at the frame closely to see the access holes to drive out the pins. Mine were not large enough for the pin (7/8 inch) to be punched from outside to inside, so I had to drive in opposite direction to get the pins out. Look at it, you will get the idea
Anyhow, it is not complicated; Just be prepared to really hit em hard and long
P.S. are your springs any good?? If you're gettin rid of 'em let me know!!!
