Vin tag decode help please

My build sheet says EB5 in the body paint code on my build sheet. The roof paint/style top code is also EB5. My car is definitely a 1970 Swinger 340. I beg to differ, 413. I could be wrong, but I don't think so this time. I'm not trying to be a butthead, and I don't mind being corrected when I screw up, but I'm real sure on this one.
