It might have been me yes Theo.
I was told ages ago that the 'Series 2' Abarths were in fact 're-built' series 1, modernised to reflect the cars that were at the time being sold in Fiat's dealerships - i.e. Series 2. In fact I think it was Mick Wood (he of Group 4 ownership) that told me as I was asking him why his car had the later series 2 rear end and lights.
To the best of my knowledge, there were no series 2 Stradales manufactured and sold, only series 1, but if anyone has any proof to the contrary then I'd be more than happy to change my belief

I heard say that there was loads of information available on the internet relating to 131 Abarths and their production numbers, but I can't find it and I've been looking for years. Interestingly though, all Stradales that have been researched (some 40 or so cars, by a lad in Australia whose Dad has three

) have chassis numbers starting 131AR00203**** or 131AR00204****, all produced in the summer of 1976 (regardless of when they may have been registered

). I don't have the chassis numbers for the competition cars, although I beleive there is a site that lists them.
The fact is though that later evolutions of the 131 Group 4 cars were vastly different to the early ones. First evolution Group 4 (1976) were very similar to the Stradale, but the last few competition cars (1980) had fuel injection, bigger brakes, different servo, different suspension, etc, etc and pushes out in excess of 250bhp, whereas the first cars ran about 150 to 180 bhp.
I'm no expert on the competition cars, so if someone has better info I'd love to see it please
