hi Dan, mcsteve here, looks like you bought the car in Chandlerville, Illinois that i posted on this site back in february. He had 2 - 1970 ss montes he bought near Alton, Illinois just to flip them. I bought the other car (red w/ black top n interior). Supposedly the rearend in my car was out of your car - 2.56 posi: my build sheet says my car was non-posi 2.56. The vin #s were only 170 cars apart built at Baltimore plant. I looked for the build sheet in usual places (front seat backs n both halves of rear seat but just used mirror under front buckets to look). Triple black car will be really cool - that car is very rebuildable. Good luck with it! Steve
