Lug nuts

[eduardotule10]

Hey guys, I'm new around, I have a 1970 Custom/20 Deluxe, med olive green, 350 cid, long bed. I live in a small city near Mexico city and I really need to tell you there's nothing much around here when we talk about truck enthusiasts. I have a lot of doubts about my truck and I hope you can help me dissipate some of them. The first one is: Though the emblems on the fenders read C/20, the vin number says my truck is a half ton. But it has a 6 lug nuts pattern, what exactly does this mean?? My truck is a 1/2 ton?? is it a 3/4?? did the guy who owned before me change the emblems?? thanks for your answers!!
