Found a document in my headliner....???

Something 55. The spring mark is covering the first letter. I assume that means 8.75 3.55?

055 is the axle assembly code for a 70 B body, 3.55 sure grip and 11" drum brakes. This would be consistent with the A36 axle code.

A36 code cars also code D56

A36? Where would that be noted? Mine says D56
