Confusing. Can't tell what RC car parts fit what. Then, in description for a 370 RC motor/gearbox, it says ( not included, motor.) I, and everyone else would love to enter a model# and have parts come up for it. When i put in FY004A, i saw some rc parts and hats and stuff. Can't find upgraded leaf springs, upgraded axels say pair. My truck has 3 axels.
