Good choice! I have the same set up from JBG on my '81 and have zero complaints. Only advice I have is to constantly check to make sure the pivot brackets that bolt to the front crossmember are always tight. Im running 35's with zero rubbing.Just pulled the trigger on the JBG BDS kit and a set of Bilsteins. Going to just flip the rear shackles for now. Gulp. Now onto building those bumpers!
Also, I would maybe think about holding off on the tie rod flip. I can send you pictures of mine but the tie rods almost sit even with tie rod under the knuckle with a drop pitman arm and I have never had an alignment issue in the 7 years I have had the lift.
