[SOLVED] Are Hepco & Becker C Bow mounts compatible with the OEM Rear Rack?

[JRD]

I have a 2017Ex and after installing the same rack, felt that the grabrail was no longer needed., so replaced it with appropriate thickness spacers.  
Maybe the black Hepco-Becker mounts could go inside the rack mountings in place of the grabrail, moving the bags inward a few inches.

Interesting. I was looking to steal space from the other direction, but that would probably work as well, and require less cutting....

I went outside and mocked it up by using washers as spacers. This will work. Will still need to cut the OEM rack at the front spacer, but it will be much less tight and preserve the weld.

As you say, it would look better if you keep the grab bar, but with the rear rack and the chrome mounting bracket you don't really notice its absence.

Edit: Please note that the highlighted numbers in the body of the picture are not ideal: they don't provide quite enough clearance from the rear fender. Also cuts the C-mount clearance from the rear shock pretty close.. The green numbers (in millimeters) on the diagram are correct for giving maximum clearance.

Edit #2: this doesn’t work. The c bow mounts fit fine (after a bit of cutting and and shimming) but the c bows themselves bump into the rear rack bolts.
