14" Rims and Larger Tires

Ok I went to the page on year thank you for that. According to the 1965 Barracuda Service Manual the axle ratios are as follows
AV-1
225 Cu. In.
Engine

Manual Trans 3.91
Optional 2.93, 3.55
Automatic Trans 2.93
Optional 3.23,3.55

This does not list a 2.93 which I believe is my stock Barracudas gear ratio. Am I missing something or should I assume a 3.23 is the correct ratio?
