Replying to BSL Adjustment FKS 140

Hey guys quick question that may have been answered before, but I just want to check again and get a clear answer on my specific specifications.

If I have FKS 140s mounted on my skis and they are mounted for Full Tilt Booters (26.5/302 BSL) is it possible for me to adjust my bindings to fit SPK Pros (26.5/305 BSL) without having to remount my bindings? Or is it even necessary for me to adjust it at all with just a difference of 5 with the BSL?

Thanks for the answers/help.
