Aftermarket turn signals - Need some help.

[CBville_imp]

Last night I was able to purchase some larger washers and mount the rear signals. However, I ran into another issue with the rear signals now. The factory honda luggage rack will not work for USA CB1100s running these Posh signals because of clearance issues. Without a spacer/base mount to push the rear signals further out, it hits the rear mount of the luggage rack.

It probably needs to be pushed out atleast 5-10mm to clear it. I was originally planning to install a Givi top box with back rest for the wife. I really liked the Honda rack because it makes a great grab rail as a bonus. Now my options are:

1. Find a nice spacer about 1cm thick to use as a base for the signals. Keep the Honda rack and install the topbox with backrest.

2. Find another rack: Hurricane or Kajima (not in love with either as they don't provide a great grab rail and max load is only 3kg, but looks like both will clear the signals).

3. Ditch the whole top box idea. Purchase new grab rails and buy a Corbin seat with back rest. This option will cost the most and I lose the luggage function. Are there any universal adjustable back rests available that mount up to grab rails? I would only go the Corbin route because of the back rest option.
