Bob M., I assume you are referring to the chrome lever and where it fits onto the splined shaft. It would be a major operation to replace that shaft, not to mention that shaft (item #19 in the drawing below) is no longer available new. The chrome control lever (item #18 in the drawing below) was still available in 1998, the part number was IH-401388-R3 and at that time cost about $62. You might be able to round up a good used shaft though.
