Looking for info

Hello all, I'm wondering if anyone has seen this or might know were it is?
I traded it to a person in 1980 for thier 73 Challenger Rallye. the new owner was going to BYU in Utah and I did see it once in Pleasanton Calif around 1984 but was on foot at work when it drove by.
Thanks for looking and any help locating it would be appreciated.

Last Calif plate was "EL DEMON"
