Jeff-
Glad to hear the control arms are holding well.
To bad the heating problem still exists.

I did some research this weekend and I know exactly how I am going to adjust my control arms. That will be a little different like you did.
The same for the internal sway bar, however I do not know exactly how I am going to hold the lower control arms together, but that will find a way out too.

Do you have any pictures of how the set-up looks now? Please post them if so.

Good luck with finding a solution for your heating problem.
