Cobra, I had the same problem on my AT-6. While two servos in the tail will work, unless your plane is already nose-heavy, you'll need considerable weight in the nose to balance.

If possible, make a lite-ply pushrod support with a hole a bit larger than the dowel, slide it down the fuselage and epoxy it across a former about halfway down. This will limit side play in the pushrod.

And/or, make a wire joiner and join the elevator halves together anyway, if its not too late.

Good Luck.
