Does anyone have any other suggestions for what I can do?

Would the powers that be there in your country be agreeable with running a Heim (spherical rod end) aircraft style rod end on that end of the drag link?

I think that a proper size heim end would fit in quite a bit closer to the pitman arm and give you the needed clearance. They get used in hotrods and race cars all the time.

I don't know anything about this source except what we read but it does give some explanation about it. http://bulletproofsteering.com/failedrodend.html

You would probably have sources there for the rod ends.
