Well that didn't take long to disassemble. Unfortunately, my '19 Corolla Hatchback uses 10mm fasteners with 14mm heads, so the bolts included with the Curt hitch, and my 8mm all thread is too small. Hardware store where I buy my metric bolts closed at 6pm, so will buy some longer grade 10.9...
I'm tackling the Hitch install this evening and finishing in the morning. I will shoot some photos. Got my hitch from etrailer, a Curt. Thanks to Archdrake, I stopped by the hardware store and got some 8x1.25pitchx 100 mm allthread and two nuts. Will do the dremeling trick to the all thread...
