Very similar. I wrapped the upper part of the bolt with some tape so it would stay put while spinning the mount into place to be tightened up.One trick I have used when installing these bumpstops (this was my third set!) is to super glue the bolt into the mount first. That way you can just twist the mount on, like the OEM mounts!
Otherwise you have to fiddle with the Allen key with 1/4 turn at a time!
