You seem to be focused on the length of the rod but, as you've stated, the trans lever is full back at WOT so the point is moot.
What you should be focused on is the "Start in 1 and floor it slap stick moves to 2nd by itself prematurely.".

What you should be focused on is the "Start in 1 and floor it slap stick moves to 2nd by itself prematurely.". Checked mounts they are good. Today I reinstalled the rod after I tweaked it so it was the same length as a stock one. I was playing with the shifter handle and noticed that sometimes I couldn't get it to fully go into 1. So I drove it. When I would put it down in 1 once I got it to fully go I noticed the accelerator pedal was almost impossible to press. I brought it back and took a look under the hood and the shift linkage and kickdown rod linkage are interfering with each other. So this must be why when you floor it in 1 it automatically moves to 2 because the kickdown rod is pushing the shift selector to the next gear. How can I fix this?

Check the shift linkage for loose or missing plastic bushings, they're known to fall out.

I think I may remove the anti-theft column lock rods and see if that helps

Do you have a 2nd person to watch what is going on? Have someone push the kickdown linkage back and forth and see what is happening down below. Is it binding on something? After you "tweaked" it, now you can't push on the accelerator. Sounds like it got worse when you adjusted the rod. Almost sounds like the kickdown is not attached at the right place. Do you have a photo where the kickdown is attached to the transmission? The kickdown lever hitting the shift lever at transmission? While car is on ramps or stands, put trans in 1st gear, move kickdown lever back and forth and see what is happening below. Use wheel chocks.

I had someone tell me to remove this rod and it would likely solve my issue.

Are you sure you have the correct throttle pressure kick down lever attached at the valve body? There are different lengths. This would change the attaching point distance of the rod. Maybe it got switched out during a trans overhaul?
Doug I'm not sure of anything. How can I tell.

Doug I'm not sure of anything. How can I tell. Good Read with some pictures on the factory stuff so you can understand what your looking at with different length throttle levers and adjustment , never mind the Lokar cable setup mentioned in the article as that is an aftermarket set up Click on link https://www.hotrod.com/articles/the-lowdown-on-stock-torqueflite-kick-down-linkage/

If you remove the lock rod remember to set the lever at the bottom of the column or the ignition will lock. Not sure I understand please explain.

The lock rod moves part of the column that allows the ignition to turn. It is an safety device the car from being started when in gear. Play with the lever and the ignition switch and you will see what I mean. If the lever on the lower column is down you can't get the key out. Ask me how I know this.

Does the rod need to be all the way up or all the way up or all the way down for everything to function?
