To transport and move my front clam I've built a wooden jig that's on castors ans also sits nicely on roof rails. If anyone wants to borrow it, I'm near Guildford. It uses 4 attachment points - 2 Front lower M8s and the bonnet stops, the latter having a bit more meat around them than the actual main mounts adjacent.
It will also stand vertically.
