mmm, don't think so? I've seen the ally blocks your talking about, and i think I've done my mounts in a similar place, there was definitely no mounting holes anywhere in the area, happy to be proved wrong though! From the pics i've seen the ally block through bolts go into threaded holes in the chassis? i thought about tracking down a kit, but will probably end up trying a few different bar diameters, so may not have ended up using much of it
