Check out ebay, there are tons of different styles to choose from. What you will discover is that none of them have the over drive button on them. I've only found one style that has the O/D button that suits our style shifter on the mustangs. They want 50 plus shipping for that. So for now i'm living with what i got.
I have a friend that took a shift bezel off a GT 5 speed and put it onto his automatic. He kept the shift boot intact and just threaded it over the top of the auto shifter. Then he bought an aftermarket shift knob and screwed it onto the top. It looks like a stick shift car at a quick glance from the outside and you really wouldn't know it was an auto unless you looked closely. I'll post a pic if he will let me.
