Those pics look like them. My MM's go from about the firewall all the way to the torque boxes. Normal ones are just long enough to overlap sub frames by 6 inches usually if that. I dont have pics of mine offhand but i can take some next week when putting the transmission back in.
Ive also noticed that the boxing on the shorter ones is smaller. Maximum Motorsports makes a great connector. These work well enough so that my door no longer tweaks when the front is lifted off the ground.
