According to FAST the alternative #12279 85G00 its the same as the RB20/RB25/KA24E
While the other alternative # 12279 58S00 lists RB25/RB26/KA24DE
Hopefully you can find out if the KA24E or DE Main Seals will work. I know the KA and SR have the same Front Main Seal but the Rears are not shared between the two as the KA has a much larger Real Seal.
