2018 f350 DRW to SRW conversion ABS issues

[dma1384@gmail.com]

Good afternoon to all. i recently decided to go from dually to single on my truck and had a donor 2017 f250 axle that i ended up using to turn my truck into single rear wheel. the swap was successful accept for one issue. my rear abs sensors are showing slower speed than the front and its messing with the module and i've been trying to use forscan to do changes and i cant seem to find where i can change the tone ring info. if anyone has any idea what i need to do please let me know. (i do have abs module from donor truck and when i install it and change as built info truck doesnt accept it keeps saying wrong configuration)
