AAM 11.5 Axle Width

I know the question has been asked many times on here about what the difference in width is between the SRW and DRW axles . I'm in the midst of doing a conversion so I took the opportunity to measure both axles to see what the difference in width is. Both axles are from 2008 3500 trucks. Hope this helps someone in the future who is looking for the info.

SRW wheel flange to wheel flange 71.5"
SRW inside rotor to inside rotor 61.25"

DRW wheel flange to wheel flange 75"
DRW inside rotor to inside rotor 59.5"
