1970 1/2 need to know exactly what I have here.

[clean68rs]

A friend is looking at a 1970 1/2 camaro to buy and would like to know just what this car came from the factory as. Here are the vin numbers and the tag numbers. First  vin 124870L523026. Here are the plate numbers  ST 70/12487/BL/21960  TR 711 535305c724168180216. The owner of the car says it might be a z28 but the steering wheel has the rs on it. It also has a ten bolt rear end. Im not sure but I thought that the z28 had a 12 bolt rear end. Any help with this would be appreciated. Thank you. Scott.
