The way he discribed it I thought he just had units. He put a 8 3/4 from duster in old lead sled'ish Pontiac and races it. Swears but the old coney suregrip! Wish I had longer to stay and shoot the sheit has so much cool stuff just layin around in the bush and sheds and All over . Thanks again for the responses.
