Alright here is the solution for the key lock-out (aka NSS)/reverse light issue with using the stock column range rod and the Hooker swap headers.
1. The bracket which mounts on the brake distribution block needs to have the ball socket moved up 1/2". I cut it along the bend and rewelded it - make sure you measure the angle first before cutting;
2. The bracket on the transmission selector switch need to be cut and moved up 1/2". Note you will need a nut that does not have an integrated washer due to the reduced threads to draw down against (and yes, you could weld the brackets together too);
3. The cross shaft which translates the movement from the shifter/transmission selector switch to the column lock-out needs to be straightened and shaped to go over the header. Guess how much clearance you need to add? That's right - 1/2"! I used a vice and a BFH to give it that sweet custom reverse banana bend;
4. The pinch nut which goes to the column rod needs to flipped to the other side of the bracket on the cross shaft. I rounded the edges off of it to reduce the risk of it binding on things; and
5. Lastly, you may find that you want to chop an inch or two off of the cross shaft that inserts into the ball socket. I took close to 2" off and ran a shorter spring. This really aided in assembly with the header in the way. You may also find that you want to chop an inch off of the bottom of the column rod - your results may vary. Measure once, cut once, weld once, measure again, and cut again.
I am running a B&M shifter and a 4L60E which may be wider at the case body location for the transmission selector switch than other GM transmissions.
