Should have left it alone.

For some reason I checked where the way tubes weld position was. The front one was at 6:00 o'clock, the back one was at about 11:00 o'clock. Since I've been have some trouble sliding the headstock, I figured I'd twist the back tube so that the weld matched the front one. It's now on the bottom, BUT the set screw that anchors the tube in place came out. Will I have to remove the roll pin from the base arm pin #29, tap the pin out to replace the set screw?

NO. It is not necessary to remove the hinge pin in order to access the set screw. However, your task will not be a simole one due to the location of the set screw and the obstruction imposed by the hinge pin. Obvious the work must be done from the underside of the Mark V...UNLESS... you can lay the Mark V on its side or invert it.

Access is easier if one raises it to vertical.
Now did repositioning help with the 'slide problem'?

Use an Allen wrench with a ball end. It may help accessing the set screw.

When I first read this I thought "gee, I don't remember having a problem tightening the set screws." Then I read more carefully and realized he actually removed the set screw. Yeah, weaving it back into that little hole would be pretty frustrating! Bill's ball-end Allen wrench suggestion would help ... also maybe shining a light through the hole from the other end to provide a clearer target.

I THINK the ONLY way to access it, is in the drill press mode. It's still in drill press mode,with a missing screw.
Going over the top of the bar allowed me to loosen it. The problem is I must have loosened it to much and it came out. So to get the set screw in STRAIGHT, the bar will have to be move out of the way.

I can feel your pain. I've not done this exact same thing but others very much like it. I do think it can be done with out taking everything apart but it will difficult. I remember once using a straw and sticking the setscrew in the straw then flexing the straw enough to get a few threads started..... perhaps something like that would work in your case.
Best of luck with this.
