@1olbull fitted a Thunderbird gear shift to his R3R with an early R3 Standard footboards conversion, he used it direct to gear shift shaft, no linkages. He then got an alloy CNC one from the UK that fits and covers the whole 865 900 Bonnie etc range but found it too chunky, but it fitted fine.
Yes @Mikethepie I was out hanging lights in my garage and stumbled on this .
I believe its a Rivco. It came 6 or 7 years ago in a box parts with a 05 I picked up. Anyway its yours if you need it. Otherwise I will mark it and hang it in the wall for someone who doesn't know he needs it yet
