I have a 2016 C-14 with the factory GIvI Top Box installed. The box has the GIvI backrest on it and I need to move the box rearward approximately 3”. It sets way too far forward toward the seat not allowing the passenger to sit strait up. I have the Whitehorse flat rack on my KLR and added the GIvI Universal mount to it and it works fine and I was going to do the same on the C-14 but Whitehorse is pit of business now and I can’t find a flat platform wide enough anywhere on th the internet. Probably should be at least 15” wide. Has anyone else here moved your mount back to gain more clearance from the back of the seat? Any ideas are certainly appreciated. My spouse loved riding the ZG 1000 for many 500mi multi day trips but with the current set-up on the C-14 100 miles it it.
