This is quite similar to the 1986 module mount. Two inexpensive flanged bronze bushings supporting the pivot stem, captured with a collar. A roller thrust bearing took the load above the steering sprocket. The stem weldment was steel and quite stong, no lower support required. This mount was very simple and robust. We could change out a module in a few minutes. Here's some pics.
