James, I can't open your picture links. Here is a cool PIC of Don racing in the rain. Notice the emblem on the front fender. I looks like the Yenko crest but larger then the 68-69 emblem. I may not be a Yenko emblem though. The red white and blue Yenko crest is on the 1968 Corvette that Don raced. I have not seen it before 1968. Anyone know what year the 68-69 style Yenko crest was first used?
