Where can I get good classix car frames?

I'm trying to get a good mustang 60-70 car frame to start a new project. Any website or yards near LA.

Mustang never had an entire frame! Its a uni-body which does have a short sub-frame under the motor.

No frame on a Mustang and no Mustang before 64. You can order a repro body 65-70 here http://www.dynacornclassicbodies.com/ford_models2.html "All Bodies are shipped FOB Camarillo, California freight prepaid, or you could make your own freight arrangements."
