Bob like you the sixties are my favorite , as my Dad started racing in 62 or 63 and we had to be at the track at 4.30 when the pit gate opened we got to see all the cars being flat towed or trailered to the track , I can still see and remember setting in the stands watching everyone pull in . it wasn't till 65 and 66 that the v8 super modifieds started cutting down the body's and 1970 was the first year the 6 cyl modifieds went to the cut down bodys so I got to see all the old jalopy to the "new" cut down super modified cars , it was a great time in my life and a great time in racing overall , Okc and Tulsa kept the 100" wheel base supers and modifieds around 1995 , in the mid 80's they even brought in the Usac dirt champ cars to race with our NCRA 100" champ dirt (super modifieds) but I still like to model the cars from the 60's early 70's
