Do you remember Jack Clevenger

I am Jack Clevenger's daughter. I am looking for any information I can find about him and/or his race car. He believe drove in the 50's and 60's and early 70's. His first car was #81 and then he changed to #5. I know he raced in southern California. I found an article which stated he called himself "Jackie Holmes." He stated he used this ***umed name to keep his dad from finding out he was racing. My dad was from Farmland Indiana. I would appreciate any information anyone can give me.
