New blistein 4600 with Moog 81074 coils .

I ordered a set of blistein 4600 with (supposedly) Moog 81074 coils for my 09 prerunner access cab v6. I can’t see any marking on the coils to indicate drivers side or passenger side . There are no painted dots to indicate which side or direction .One of them appears to be clocked right with the bottom end facing the back but the other one may not be clocked correctly. They came pre assembled . So should bottom ends of the coil face the back ? If they don’t , does the coil over need to be completely taken apart and turned ? Thanks for any info .
