I installed a RS kit on a '94 pickup, just milled out the holes in the spring plate about 3/8" on each side to allow for the wider bolt spacing around the wider perch. Also saw another axle where the guy just used a grinder to notch the spring perch sides enougn to get the u-bolts in the narrow holes. Both ways work fine, I could mill the holes out on your plates or just have a set of proper width spring plates made in the first place:
