Billy 5100 rear shock install

just installed the billy 5100 I got in the mail today. My question is does it matter what side the shocks go on. For some reason I read somewhere that it does but if I remember correctly it was on a gen 1. I couldn't imagine that it would make a difference on which side they go on. Another question I know the torque specs say 20lbs. It's kind of hard to gage 20 lbs since I don't have a wrench torque. The resistance feels the same until you bottom out the rubber spacers which I know that is not correct. So I just so I just turned the nut down so that a 1/4 inch of the threads were showing. The bushing are compressed I just want to make sure I am doing this correctly. Any info would be greatly appreciated.

 

pick up a cheap torque wrench for $20 to get within range. comes in use if you plan on working on your truck in the future.. if not, I just crank them down...hard

 

I did get a torque wrench but just for the bottom bolts. I would need sn open end torque wrench to torque the top bolts that why i was asking. Because the stud turns with the bolt if u turn just the nut
