Careful doing business with the safehouse guy (if it's in cali)Thanks everyone! I ended up passing on these for a haul of Safe House's, but this is good to know. I have a lot of Frogs in my collection that have a similar hinge that I know I'm going to snap one of these nubs someday. I hope this helps others that run into the issue in the future.
BTW, @Wavecloud, I love those Racing Jackets in your avatar. I have a pair of Bengals that I haven't worn in years, but might need to bring them out of retirement for some select rides this year.
