the cv yoke doesn't take u-joint straps. it has smooth bolt holes. bolts go through the yoke and thread into the cv end of the driveshaft. thanks for the offer but i bought one last night on ebay.
Well it depends on what sort of double cardan you have (which depends on what type of SYE you are using). If your eBay flange doesn't work out, I have a driveshaft with the flat flange for the hack-and-tap for sale in another thread.
