Jerry will help you out, but if you have not done it before, it can get scary.
Jim Carters is in in your area, you might see what they would charge to just do it. I think they do truck work and are a supporter of the Stovebolt group.
If they won't do it, they will know who will. Great group and you will meet Jim at the Reunion this September.
