Here is my guess on numbers.
I would think the L89 production would roughly follow the overall Chevelle production of aprox 20% convertibles and 5% El Caminos.
So, 400 L89 Chevelles would be aprox 80 L89 convertibles and 20 L89 El Caminos. This estimate sounds better to me then just pulling numbers out of thin air.
