I have a similar issue. Based on the previous posts on b7000 steering the B7100 steering will work if you remove the dash plate and then re-weld it in the needed position. That is what I'm planing to do.
What I'd still like to know if the pinion arm and steering wheel on the B7000 will still work? I have not
been able to cross reference this. Hopefully someone who knows more can comment.
