The late 72 and 73 are a 1 piece rotor. The 69-72 early are a 2 piece rotor.
The complication is that the aftermarket figured out that they could inexpensively make a 1-piece rotor to fit 69-72 applications using the same casting as the 1973 rotor, if one of the bearing races was machined to fit the earlier bearing. Since both versions have the same casting numbers, it's difficult to tell them apart.

Just looking at a few items on Rockauto and noticed that they have Wagner 1793 C- body rotors for less than $25. That is a pretty good deal.
These on sale Wagner rotors have all gone now. I am pretty sure that they were the correct ones for 1973 C-bodies with the larger bearings.
If you need the rotors for earlier than 1973 C-bodies look at the listing for 1971 C-body cars. They will be correct.
There is a similar issue with the brake pads for 69 Imperials. Brake pads that Rockauto lists (D39) are not correct for the Budd brakes. They are correct for the Kelsey Hayes brakes of 1970 and later. The correct pads for the Budd brakes are D10 which Rockauto does not carry.
