my 66 sits to low for me to slide under. so what few times i've had it up on jack stands i've looked for those axle numbers. well i finally found them with a small wire brush an a flash light holding the light so i could see the profile of the numbers. i thought the numbers would be alot larger. so what i found is BA 0211 G. so am i right in the decode BA is a 1966 3.08 non posi an 0211 is feb 11th. an G is detroit gear an axle. if i'm right this is the original axle for my 66 that was made 0218 02C on the cowl tag.
