It seems like you haven’t tried to buy OEM parts from ANY local parts store from ANYWHERE since February 2020. Good luck finding a round or square back that is in stock. I honestly don’t remember the last time I got an OE part in a day. Consumables and universal parts is all parts houses seem to have on hand these days.
The whole argument is dead, “Keep it stock so you can get parts in Anytown, USA if you break down on a long road trip.” :BangHead:
