I had a 1960 Chevrolet LCF L80 series, road tractor. It had the Torsion Bar front suspension. Sweetest riding "Big Truck', I've ever owned. It had power steering, & full air brakes,and it was carrying a big block 348. I also had a 1964 Chevrolet LCF L60 series, that was air/over hdraulic. I had no problems, with this truck either. I especially liked having another truck, equipted, with an air compressor. Any big truck repair center, should be able to locate parts, for these trucks. A Chevrolet Parts Catalog, for these years,with part numbers, will always give you an advantage, when parts hunting.
