I noticed when I dropped the turbo 400 from the 72 there were 2 cables attached to the shifter linkage. The one went to the floor shifter and the second one to the steering column. When putting the 200r4 in its place will I still use the column cable and will I need to do any other changes. I think this cable is for the shifter lockout with key off? I would think I should still use it so it only starts in park and neutral if that is its function.

The cable to the column is to lock the shifter with the key off. The neutral safety switch is mounted on the shifter assy, so the cable itself will have no effect on whether or not it starts in any gear other than park or neutral.
The cable simply keeps you(or anyone) from moving the shifter out of park without the key in the "ON" position, and it also keeps you from turning the key to "Lock" unless the shifter is in Park.
Depending on what kind of external linkage you use with the 2004R, you may be able to retain the cable feature, and you may not....at least not without some modification. If you are able to use your original 400 shift linkage that bolts to the trans, then you should be good to go with the lock-out cable.

Thanks Joel, I got a different external linkage part for the 200r4 that came with the new trans. I'll have to see whether I can still use the lockout cable or not when its time to go back together. I'm hoping it will still be usable. Just a good feature for safety.

I had to make my own bracket for the lock-out cable. It was pretty simple, I used the original bracket to start with and changed the moiunting holes to match the new trans pan. Then I made some small alterations in the angle until it worked. I will see if I can find the drawings. I ended up making several later on for other guys. After I made them I fit them on my car to make the final adjustments before I sent them to them but I am sure you could do that if I find the drawings.

Brian,
Thanks. Look forward to getting a drawing and saving some design time. whenever possible I like to eliminate trial and error! And this project is getting very long as it is!

I found two of the drawings. Evidently I never finshed converting the third peice to jpeg. I will try to find my sketch and do that.
Here are the other two for now:
