K10 k20 4wd 4x4 power steering conversion questions

[raylube]

Recently installed cap fab ps plate adapter on my 64 k20. Truck has open knuckle Dana 44 ,79 k20 gear box,6 inch lift springs from tuff country for 72 pick up with dropped pitman and raised steering arm. Drag link is sitting level with ground. Ps plate was installed as per Aotte1 measurement as well as others that I have looked at on this site.
Question #1. What are people doing with the bumper bracket?
Question #2. When I adjust drag link for full turns the threads on the sleeve leave more of a gap inside about a 1 1/4 inch compared to the 1/2 inch on the stock height, see photo. Is that enough threads or should I move the box or find a bigger sleeve? Not worried about centering steering wheel as I can adjust at ujoint or wheel.
