Pics of 114, in '65 show white on the bottom.
Be careful going by the SFM number as the finished dates were all over the place. For instance, 114 was finished on 4/26/65, yet 163 was finished on 4/23/65. Also, 159 was finished the same day as 114.
Stan, considering your car was finished in March, I'd say white bottom would be acceptable.
