I ran 660s on a tunnel ram years ago. Linkage was a simple T setup with the top of the T hooking to the throttle arms and the stock cable pulling on the bottom of the T. Stock bracket for the cable. For fuel I ran a single banjo and a double banjo in -6 size. Sorry,can't tell ya where to find but wouldn't be hard to make either. Still have the banjos and the 660s.
