Thanks for the information. The front and rear axle in the 63 scout bot have tags that say 4.27 and the 47-11 but don't know what the 47-11 means. Here are pictures of the numbers and locations I do not see any - number anywhere. These should be straight forward rebuild then if they are plain DANA 27s and i know the years. is there any doc that might show the part numbers that are needed?
