I would suggest giving Jim & Jason Smith (father/son) at The Hot Rod Garage a call. They are a Nationally renowned shop who is located in San Springs (outside of Tulsa, Ok) so they fairly close to you.

I have known them all my life and they "know" old cars better than most. Jim has built many 32s so I am confident he can suggest a solid recommendation for you regarding running boards or anything else you might need for that matter.
