What is involved in changing the bushings in the arms?

Do you have to remove the shells and install new ones?

If so, do you have to support the arm sides to press them out and in?

Sorry, but I have not taken them out to look.

I think that all of the bolts will have to be cut or broken to remove also.

Love this 43 year old stuff.

This will help. I did mine this way.

A machine shop took mine out and I used a vice, socket and a hammer to install the new ones.
