early 1969 L-46 pulleys Question

[Daniel T.]

Gentlemen, My car started life with an L46 option. It also came with options N40 power steering and C60 A/C. The pulleys on the crank and water pump appear to be configured correctly, however they do not appear to be deep groove pulleys. My question is, did the 69 L-46 with A/C and power steering options use the deep groove pulleys. Thanks for any help here I've seen alot of discussion on this but no definite answer to this question.
