Lemon Grove, CA is not far from Rudy Phillips in Ramona (San Diego area, but east of there, up in the mountains). Back in the early 1980's, at a SoCal KFOC meet, the former owner of Lemon Grove Motors came to one of our meets and talked about his KF dealership. He had a few of these frames (I own a pair now, thanks to him). His name escapes me, maybe one of the old-timers from SoCal can remember? In a box of old photos somewhere, I have a pic of him from that meet.
