PBR caliper mounting bracket differences (9 bolt to 4th gen 10 bolt)

I have PBR calipers mounted on A 9 bolt posi right now. I may pick up a 4th gen 10 bolt. Are there differences in the way they bolt on or is it just a matter of me unbolting them from the 9 bolt and bolting them onto the 10 bolt? Thanks.
