They are highly rated, their due durometer rating for the bushes used in their mounts are very stiff. When I bought mine the bushes were only available in red but they now have them in black too
Can't really see the gearbox side mount but it's of the same design. As for the dog bone mount, mine have powerflex and superpro bushes. As for the gearbox thread you can try helicoil it.
