60 on center qc question

[AH55]

Hey guys,
Getting a quickchange rearend used for a BMS mod. It needs to be 60" on center. I dont have it yet, but am told it has a 2" offset. Does anybody know what length axles and tubes to make it 60 on center? Cant seem to find any info on the manufacturer sites. Thanks in advance for your help.
