Borgeson/Bergman Steering box kit

I Tried to PM you.. but the inbox is full.. I am in but just have a couple questions first.

A - I am changing to 73 & up large spindle knuckles.. will this affect my center drag link and pitman arm?
Using 73 and up spindles does not require you to change the pitman, centerlink and idler.
B - Are we talking about the kit that has all the necessary fittings and adapters?
Kit will include, a box, direct fit coupler and line kit.

C- I have TTI headers on my small block, are there any issues with those?
No issues.
