Yup no worries. I also thought I was going crazy. I tried at home with my vise and took them to work using my press. I just couldn't get them in smoothly. I gave up and took them to my local Hot Rod shop and he confirmed that they are too big. They may work but the size is not ideal according to my shop whom i really trust.
I'm hoping he documents the starting ODof the bushing, ID of the arms and how much he had to mill. If he does I will post them and write CZP an email.
