There are plenty around here, and have a website if there are not any close to you. You can also try the little mom and pop hardware stores, big box stores usually dont carry this size, but the small places just might.

Report back with what size actually fits and doesn't leak. m12 seems too small, and I have my notes saying m16x1.5 fit.
I have 3x 3/8 BSPT plugs in the t-stat housing now and they don't leak. And I was mistaken m12x1.25 is the ECU coolant temp sensor, m16x1.5 is the cold start timer switch(edited post), and the coolant line to the turbo is 1/4 BSPT
