most shafts nowadays are paralell, you will be waiting for a while until you find some on Ebay. Try getting some cheap Hogan blades with Apex shafts, they are taper
better still, buy one ex dem Hogan blade and slot into your won as a dem, r=thats what I did, it took me a few months but I blagged about 1o different shafts from single irons off Ebay and tested them at different lengths and weights, and grips, took ages though but worth it.
