I've been looking for a heater box to go in my 68 stang. I've found them at everysite ive gone too, but none of them are for cars that have factory airconditioning, they are all for cars w/o a/c.  It will not work because the fan on a factory a/c car is in a different spot  I have searched everywere.  If any of you have one, or know of anywhere i can get one it would be appriciated

Also, my car no longer has a/c

thanks,
