Wheel offset, PCD and centre bore

What are these critical dimensions for a standard 200 Cup wheel (not Speedline)? Someone at a 'dealership' has told me that the offset is et50! but from the more reliable info I'm reading here, am I right in assuming that they're the same et68 offset as the 197 rims? Help!!! I'm confused.

I feel sure they will be the same as the 197:

ET 68
PCD 108 x 5 stud
Centre bore 60.1
