Switching from duals to single

[77c10diesel]

I am looking at several 4 door trucks and I would prefer to get one that is not a dually, however they seem harder to find.
If it is a 2wd for the front wouldn't I just swap to SRW rotors?
What about the rear? It it just remove the duals and put on singles or is it more involved?

if its a 14 bolt 10.5" the rear end is 4" narrower than a srw.  So you would need 2" spacers to align the tires front and rear.
