You could make your own. Just center the steering wheel, point the wheels straight ahead, measure the distance between the pitman arm center and the steering arm. Then take your old drag link to your friendly tig welder and have him work some magic on it. That's what I did, and for $20 I have my "custom" drag link.
You can also mix or match the ends this ways too. If you want to get fancy, you could put in an adjustable link.
