Somehow in my moves I have lost the large nut that attaches the steering arm to the steering box shaft. I think all 108/111 power steering boxes would be the same. I can measure the shaft if there is any question. Glad to pay reasonable price and shipping.

Any old time hardware stores? up here they have all kinds of metric nuts.

You might try McMaster Carr located in Santa Fe Springs, California. They are the “king” of industrial hardware stores and sell in small quantities. They have a website.
