Unfortunately that does not work without modification on the SLC Side Carriers.
I have tried it, and it doesnt work plug and play.
As far as my personal research found out, there is not a single solution to combining the SLC Sidecarriers (which are aesthetically the nicest in my view) with a rear carrier.
Also, the original Honda rear carrier is the most stabil takes up to 8kg which is a lot mor then most (or even all) others.
Yet, in winter, I will modify my SLC side carriers, as there is a part on each sid that has to be cut of, made shorter, again welded and have it powder-coated again.
I think, its worth the endeavour, because it will be the best solution for this combination of sides and rear racks.
