Well, here's a start: 544 '67 GS 340 Californias were made with the 340; my GS CA had the 2-spd ST300 trans with Switch Pitch converter, manual steering and manual drum brakes (I sold the car 18 months ago). I don't know how many "non-Californias" were produced; you might want to post your question on www.v8buick.com
