The 4000 B is the part number for the diff. In this case 6.66 to 1 ratio.
Has 640 stamped on the back of the housing, which means 6 teeth pinion and 40 crown wheel . Outside dia. of diff housing will be 14 -7/8'' across. This assembly supplied for service from serial #3000.
The front diff will be tagged 3000 C , if the tag is still there. The gen pulley you are going to swap over, just be careful it is not screwed onto the shaft, some are some are just keyed on, a trap for young
players is to put a puller on a screwed on pulley and smash it to bits, I know I have done it!

Andrew,

You were right about the front axle. Here is a picture of the front tag. This exercise is like a treasure hunt.
