I know alignment is needed whenever the structs had been takingb off. But what if I only touched the rear, and I did not touch teh cam adjustment bolt nor teh toe adjustment bolt?

All I did was to take out the two bolts that hold the lower arm and the rear struct assembly, and also the bolt that hold the lower arm and the brake (or whatever you call it). I did that and twisted out springs from the bottom to swap with different springs (I have Cusco Zero 2R's)... I know, the height may be off a bit, but I kept it as close to what I had as possible.... Do you think I still need to do the alignment again? And I guess it front and rear has to be done at the same time as well huh?
