Thanks for the info Mick. I'm not being critical, just want to understand how this will work.
I went back and looked at your posting from Sunday and realized that there are two bolts going up through the bottom of the box holding the Howe device in place in the box. I'm guessing that those two bolts will also be used to mount the box to the chassis?
The box will be mounted inline in the column. Hopefully I will make some progress on that today and it will be clearer. Thank you for your thoughts.
