If I'm not mistaken...Vern Trider was at the corner of Euclid and Lincoln in Anaheim. It eventually became Woody Chevrolet...and now it's something else...
If there was a Cone Bros. In Anaheim (Sounds familiar)...I would suspect that it was on Anaheim Blvd near downtown..I think that Hardin Olds (where I worked) eventually took over their lot...before Hardin moved down the street...
Cone Chevrolet in Fullerton did have quite a few high performance cars...
