Replying to 90mm FKS brakes on a 96mm ski: bending required? or am I ok?

So I want to get a pair of ON3P JMOs with their sale. I have a pair of fks 140 with 90mm brakes, and a pair of FKS 180 XXL's with 115mm brakes. I want to save the 180's for a pow ski (tbd), and 115mm on 96mm would hang out wayyyy too much. Will the 90mm brake fit the 96mm waist of the JMO's? (mounted -1 from suggestions so maybe 98-100mm where it actually sits) or will I have to take them apart/bend them like I've had to do with all my old pivots...
