Thanks for this info. There is an NOS 26.8 Taihei Compe on eBay for $50 with shipping, but I still need to confirm the correct size, as my calipers are only showing 26.2. Also, I would love to find a fluted post for cheap as I like the looks and this won't be an original build / restoration.
That said, do you know what the original seat would have been?
