1970 Dodge challenger V code $3,000

i am looking at a 70 challenger that is completly dissassembled. it says r/t on the grille, and it has clear title, . what is the difference between a r/t, and a v-code car. better yet, what is a v-code car? were all r/t a 6 pk cars? this one i am looking at has everything to put back together, minus the driver side headlight bezel, quarters.lol the doors need help, fenders nee help. trunk needs replaced, but the floors are mint,. go figure.lol
if it is a real r/t what should the vin be? and what if it was a supposed v-code? thanks for the help
