Mazda Dealer is best place when you can't find it elsewhere .... happy it turned out for you . Probably some home-made mod made to it with taking off the thermo .... not sure though .... do run with it though I strongly suggest

 

Hey Leanne,
I just bought a user 92 Model 929, same color as yours.. I have been trying to purchase parts which seem pretty expensive. I looked at your pictures and wish I was young again!!

AAAHHHHHHHHHHH,
