Hi, Any advice you can give me on this would be appreciated. This is a long deserted project that has been restarted. Inner sills were replace years ago but outer are in the garage. Lower A post also repaired, floor pan just patched. I have the door fitted with a nice gap all the way around, and am now trying to fit the outer sill. It would seem logical that the gap between the bottom of the door and the top of the outer sill should be the same from front to rear but if I do that, the bottom of the outer sill does not line up evenly with the bottom edge of the inner sill (from front to rear) That made me curious when I read that there is a "natural gap between the bottom of the inner and outer sills is just over a 1/4" What does that mean exactly? Suggestion?
