Have you checked the size of the opening? Will the shaft slip in or will you need to thread it? If the clamps are tight at the steering wheel and down by the steering box it will probably be fine other than threads on the shaft cutting into the brass if it rotates. My guess Toyota has out sourced this part which I guess is better than NLA. The handle is painted, can't tell if it's still cast pot metal or forged steel. I like the old polished pot metal but it did bend and break pretty easy.
Is this thread supposed to be there ? Cool Cruisers picture shows 1958 -up has this thread ? Toyota part 84310-60022 comes with no threads. I looked at my 1969 and cannot tell if it is threaded or not. Also, seems it would be best unthreaded as the column shift pivots on this and you would always put pressure on these threads. Anyone ?
Update.... I spoke with a guy from Cruiser Corps today and even though the picture on the site looks like it is threaded, IT IS NOT. He pulled one out to look at it , and, NO threads. So, it is a pin and smooth sided item. As I said , makes sense as the shift pivots there, threads would be impractical.
