I have a flat-sided Improved Car crankshaft for sale. This came out of my 26 Tudor engine(which got a new SCAT crank). I had this maganafluxed and then the journals re-ground. The pic of the tag verify the work by a local outfit experienced in Model T work. I was going to keep it for a future project, but that future project has arrived and doesn't need a new crankshaft after all. So, there's no sense letting it just gather dust in the garage. $350 plus shipping. Contact info: ctn87710ATcenturytel.net (replace AT with @)
By the way the pics showing what looks like light rust on the journals is just reflecting the wood table top. Can send more pics to verify this if desired.
