I just finished doing the front corners of my 54 cab and all the panels need some minor work to make fit right. The worst seem to be the inner cowl panels as the floor had an inboard camber that the replacement panels did not accomodate. I had to splice in a few small pieces to fill that gap. No big deal really. The worst panel I have encountered so far was the inner-to-outer cowl for the right side. This one I had to do major modification to for it to fit close to the original. I do not know if it is the panels fault or the way the truck was made but at least there are replacements for them.

If you are having this type of work done by someone else it will cost you a couple of grand. I would suggest you put that money into a good angle grinder, a MIG welder with a gas bottle and some ancillary tools and learn to do it yourself. That is what I am doing. I have never done anything this severe in the past but it realy is not that hard and can be fun.

After you are done then you can enrich the body may and have him paint it for you.

Good luck
