I made the original post about them looking for a later Thunderbird.
It isn't listed as one of the bikes they need anymore, so either they've made it or decided not to. Give them a call (be warned, their customer service is horrible). I added a latch to mine to accept the corbin (and have 2 corbins), so I haven't kept tabs on whether they came out with one to fit without modification or not.
Here are the bikes they are looking for now:
