63/64 13 and 14'' sbp wheel question

I got the original service manual and it denies 14'' ;(. It will be allright for the technical approval if I can show that the upcoming models in 64/65/66 had the extra option to be driven with 14''. Or that this wheels could be bought as an accesory part by chrysler or a third person manufacturer in 63/64/65. I will try it with the Chrysler Parts Hi-Performance&Dress up Parts book. It has some 14'' racing wheels listed.
