Mr. Goodwrench, Chevrolet Low Cab Forward trucks, are actually "L" series trucks, & not "C" series trucks(which are regular conventionals). so if your truck is indeed a Low Cab forward "LCF", it's actually a L80. I've owned five of them, a 1960 Chevy L80 tractor, 1965 L80 Holmes Wrecker, 1964 L60H equipment hauler/cab, & chassis, & a couple of 1965 L60's. You can see three of them, in this link,
