This is making sense now!! I was trying to place a Ken Smith aftermarket crank?? Was almost going to ask for more details if you knew any. The Randy Smith crank is difficult to find, and I don't think he made very many. I'm sure you know that the biggest attribute of it is that it's straight and strong!! I have one, but hanging on to it. I often wonder how many might have been installed in engines already, and forgotten about?
Good luck with the search,
