Per Chevy info 9737 was available on Camaro only with 9560 or 9561. It was called "SPORTSCAR CONVERSION/YENKO". As a result it is quite rare; very few non-Yenko COPOs had it. Berger and few other dealers knew of it; documentation for these cars is quite hard to come by.
There were at least 3 prices for the option during the model year: $126.40, $160.10, $184.34. Chevrolet Shipper Copies for many of Yenkos' COPOs exist; cars in the last order batch had the factory in-dash tach but it is not listed on the Shipper. It is thought 9737 was amended to include the factory tach, which was made available at Yenkos' request.
