Help! So... to this illustrious group! I've spent a couple of nights reading through but I need help!!
I'm having a 'debate' with the FIA regarding 2.5L engine running in a ST in 1971.
Does anyone have 'in period' photo's or evidence of a 2.5 ST running in 1971 at an international sporting event?
So grateful if anyone does! the Porsche Book seems to refer to this but it other sources I need to back up the case!
