    I have a 71 duster drag car and when it rolls backwards it turns slightly to the left, steering wheel turns clockwise.
    What’s adjusted wrong?
    I don’t have any adjustment numbers, front end was set up many years ago and is somewhat worn out.
    Thanks

    It seems an alignment is in order , turning to the most caster , I think :steering:

    I know it’s not the brakes, they are Strang and have very little drag. I’m going with the caster, more on one side than the other maybe?

      Under thread tools below the title to the right. I think you can see that as a member.

      I did try to fix it, couldn’t figure it out. Now I’ll know what to do next time.
      Thanks again toolmanmike.
