Question about 1970 Superbee broadcast sheet

Can someone please help me understand (1) item on my 1970 Superbee Lynch Rd broadcast sheet ?

On line (2), under Axle, it shows 56 (D56).
On line (4) of the BC sheet it does show 82 under axle.

My fender tag shows 082 --> Fender Tag Line 2 from the top reads: 122 082 676

Main question: What's does 56 under axle on line (2) of BC Sheet represent ?


Thanks for any info.

Gary

D56 is the differential ratio, 3.54 for a Dana, 3.55 for an 8 3/4".

082 on the tag & sheet are the last three digits of the part number for the differential assembly - Dana with 3.54 Sure-Grip & 11" drum brakes.

Thank You Very Much
