I'll start looking for the newer short bolt and recessed nut then.
Thanks for helping me sort this all out everyone.
Just about the only likelihood is that the hardware was switched. Most likely it's a mixed set from two generations.
You have a pretty easy choice. You can buy or improvise a stabilizer bushing as we described earlier, or if the non-threaded part is short enough cut the bolt and buy a recessed nut.
