Where to find these console nuts?

Some of the hardware that the mfgrs use is special. Speedy nuts for pot metal plastic posts with unconventional thread cutting ( like 3 to 6 t.p.i. ) is just one example.
We can substitute those with standard hardware in some applications.
The smaller pot metal posts at the shifter bezel are easier to break off than the larger ones at console top plates even when using the correct hardware.
Good luck with it.
