That also. But I don't remember many of them being built for the first few years. I could be wrong but all I remember was a ton of F-bodies showing up with the 993/624/041 and 882 400 cu in combos. My old car (Huntzberrys current multi colored one) was Kronbitters first one built. At that time it was white.. Pat built it for himself. Earl Roes current blue car was the second one.
