What MasterSbilt_Racer said is correct for the S7 spindle package. I can't remember off hand what the old style spindles called for on RF CA lengths but it was different. Left side stayed the same with the switch to S7.
For what it's worth it isn't uncommon to see 8.25" upper on the right front with the S7 and then use a spacer or shims to get your camber back where you want it. This helps with camber gain if that's what floats your boat.
