I know I don’t have much of a Griso following here because of the haters in the Ghetto, but I just designed and made some single hole adapters to sell on the online STORE here; https://gtmotocycles.com/products/gtm-griso-turn-signal-adapter - shown below.
They’ll accept most any M8 aftermarket turn signal and come with the stainless nut(s) as shown. Turn signal not included of course, but we sell them.
