Hi; my account has not yet been activated for posting by the admins, so I cannot yet respond to your question publicly.
To answer your question regarding our product, no, the 1979 to 2004 Mustang knobs will NOT fit. The Contour uses a different thread size.
We can make a knob threaded to fit the Contour. We make knobs to fit vehicles made by 22 different manufacturers, and do lots of custom threading work too. So threading is not the issue. But we do not advertise a knob for Contours because of the reverse lockout on those cars.
Are knob have a flat surface on the bottom, and do not have the recess found on most factory knobs of cars equipped with reverse lockout.
Will our knob work with your lockout? Maybe, but I don't know for sure. Which is why I don't even attempt to sell these for Contours.
A user on this board bought one in spite of my disclaimer about the lockout, saying he wanted to see if he could get it to work anyway. His user name is mrrockwood.
I don't know if he was able to get it to work, because I never heard back from him, and he hasn't posted here about it since he purchased the knob.
Thanks for asking about our product! Hope this was helpful.
Best regards,
Marcus McLaughlin
