2 of my co-workers used to work at Swift Dodge and both remember the car in question. I am attaching a picture of one of them, back in the day. Maybe he can be of use in verifying this car once and for all. Here is his info he sent me:

I used to work for Lee Cameron in 1972-3. Worked on this car, rode in it at Sac raceway. It’s interesting to see it after all these years. Loren Lingren [lclingren@sbcglobal.net]
