Can anyone comment on how to identify compatible parts for a vintage K45 mixer? I have just purchased a lovely old mixer, and it really needs new rubber feet. I am also thinking of getting a 4.5 quart bowl for it (it came with the 4 quart), and a shield to go on top of at least one of the two bowls. I may even branch out to getting some attachments -- I have read that all the attachments (that connect on the front) are compatible between older and newer models.

Thank you for any advice! :)
