    This thread is getting traction now.
    I was curious on non RSR chassis cars were raced as RSR spec in 73-75? Somewhat like ST cars were from 70-72
    911 1972S 2.8 Race car SOLD
    911 1972T 2.5
    911 1965 300760 SOLD
    911 1971S S/T 2.5
    914-6 1970 GT 2.5
    Look for me at a track near you!

    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
