This isn't tough. You have the makings of a fine 160-10 meter antenna.

Step 1 - add wire to run the vertical leg back up toward the top to make it
a total of 135 feet long. (linear loading)

Step 2 - feed it at the top center with 450 ohm ladder line (no radials or
ground plane needed now) Run the ladder line away at an angle to be
equidistant from the legs of the antenna and put a twist in the line about
once every two feet.

Step 3 - run the ladder line back to a 1:1 current balun as close to the
shack as you can (Centaur had some nice big ones)

Step 4 - coax to the tuner in the shack. You may not even need the tuner on
160.

Step 5 - enjoy. I do.
