trans code?

[crazyhawk]

I found my broadcast sheet in the dashboard the other day. On line 2, it says "axle 55". On line 4 of the sheet, it says "axle 0*4"(can't read middle digit). Can someone tell me what those mean? I have a '73 Challenger Rallye's with the 340 and 727 slap Stik. Would appreciate any info.

I believe it is the last three digits off the diff part number used by workers to select the correct rear axle.
