Automatic to manual swap

The bushing is solid bronze my first though as to mill the bushing o fit but wasnt too sure if that would affect anything on how everything would perform
I turned down a bushing in my lathe to fit the hole in a 318 I used in my 65 Barracuda years ago.The 318 was from an automatic duster. It worked fine and I used it for over 10 years until I sold the car and it was still good then.I just used a stock bushing and made it a little thinner on the outside.
