OK, my bad for not reading your post correctly dang

I did a little research and found that your Dual Shoe drum and shoes (Group 5.610 in the parts books) are the same from 1951 to at least 1967. Knowing this I randomly looked at the 1959 Spec found at the GM Heritage Center and found the thickness listed on their page 52 of 83.

Sorry for the confusion...
