You might try to get hold of Pat York. He is in the Elkhart area.The last I knew he had the restored Welsh Leffler car. He might have the info you want.
Yes it was my uncle George Toney, he would later have the KennyJarret Farms sprinters in Usac. I believe you and him were together on the Mike Swinford 43 shores car .
Yes, it was George Toney. I used to help on Rich's car when they came to PA to race....still friends with Rich.....friends made in this sport last a lifetime.
