Glove box to hinge looks like a 10-32 x 3/8" shoulder screw. My taps only go to 1/2 is, steering column center bolt looks like 9/16 NF threads jamp type nut (thinner then regular) BUT it might even be finer threads. I would get it in a grade 8 since it has to pull the wheel down on the shaft threads. Aftermarket nut was probably made off shore, I've had problems with them too cross threading or being just enough off to mess up the threads.
