Narrowing rearend

Im working on a ram daytona right now and i need to narrow the rearend. Were bodied and running 24x9.5 wheels with +25mm offset. Im seeing anywhere from 6-10'' being taken out of the rearends, does anybody have a for sure measurement?

Does the ram daytona have a different rear end width than the regular ram rear ends?

I know the ones ive done here, i narrow 4" per side on 24x9 wheels... but the daytona may be different?

i was thinking that but i cant find anything online to say it is any different. 8'' is what i measured but all the other measurements people were doing is making me 2nd guess

hmmm, weird.

Im wondering if they have a different rear end housing?
