Lookin' for HighSchool '57 Ford Custom 300

I'm originally from Oklahoma and looking for a particular car I had while attending High School there. It is or was a '57 Ford 2dr post. At the time I bought it, I was told it was called a businessmans sedan and that it came without a back seat. By the time I bought it, it had a back seat, Keystone mags, silver paint and a black vinyl top. Also, the entire front cap tilted forward. It had a 289 from a mustang and had Cobra valve covers. At the time I had it, it was a 4 speed on the floor. The interior was Black Vinyl. I loved that car and now I'm 55 and I want it back. I saw it for the last time on a used car lot in Lawton, Oklahoma in 1970. If anyone knows where that particular car can be found, please let me know.
Thanks
