69 Camaro steering column install question

[CSG]

I am instailing an Ididit tilt column into my DSE subframed Camaro. On the bracket for the column (not the firewall piece) there is around 3/4" of fore/aft adjustment in the slots. Is there a certain place where I should be within this range? I have the DSE steering shaft and I have to push the column pretty far towards the front of the car to get enough steering shaft into each u-joint for me to be comfortable. I am going to seal weld the u-joints to the shaft so I don't need full engagement but I would still like 70% or so at the joints and 100% at the column interface and rack interface. If I need to have the column mount in a different spot in the adjustment range then I can just buy a longer DD shaft & cut it to my desired length.
