Noobie here. First post. I am changing the shocks on my 1982 FJ40. Ordered Old Man Emu shocks and anticipate they will arrive any day. I noticed when I removed the old shocks that all had a washer on both sides of the shock bushing except the rear uppers. These had no inside washer, but only the outside washer. Is this normal, or should I add an inside washer when I put the new shocks on? Also, my current hardware is a lock washer and nut to secure the shocks. Should I switch to Neoprene locking nuts or stick with the same setup? Thanks for any advice.
