I have a brand new Nomad LT sidemount rig. Has not seen water as made the switch to a Stealth.
As you can see in the pic, There are 2 modifications made. The first being a change in bungee, all that was done was replaced the dive rite bungee for some that is a bit more robust. The second is the dump valve pull cord has been replaced with a length of line, This line has yet to be cut as the rig is not being used.
Here is the pic

And a link to more info on the rig
