It is almost impossible to get any firm information on how many or which non RSR's raced as RSR's. There would have been quite a number of them, especially by 1975 or later but confirmation can only come from knowing the history of specific cars - which with race cars is very difficult.
that is because from the very first of the 911's they were continually upgraded. Certainly LWB cars were upgraded to RSR 2.9 spec RSR3.0 and later to 935 including right through to tube frame IMSA cars. I recall I even seen references to a SWB upgraded to full 935 specs somewhere
Once the parts were available it was a matter of putting them on an existing tub and going racing
There are a number of histories of the factory built ones around but this part of it is very under researched and difficult to pin down
Here's an interesting factory photo posted by Kobus Cantraine on his Instagram account
