I contacted your costumer service number and was fortunate to speak with Michael P. He had me measure the part that didn’t fit and send him a picture. He was able to find one a little bigger and sent it out to me. The newer, larger part fit much better and I was able to get it attached to the mixer. This is a great mixer that my mother gave me for my bridal shower over 50 years ago and still works like a charm! Thank you to Michael P for some crazy good customer service!
