Having used an inner to outer panel from CD/CP among others when I was restoring my cab I can say that every panel had to be worked a little to obtain the best fit. These trucks were not made using computer controlled equipment and cannot be expected to be the same from truck to truck but they are close. If you are looking for panels that fit your truck exactly I think you will be dissappointed in every supplier. I recall having to section and reweld the right side inner to outer panel make it fit my application. Goes with the territory I afraid. I will give a thumbs up to Classic Parts and most of the other suppliers for even being there to provide needed parts for our hobby. Sounds like CP is doing all they can for you.
