Just put a set of Classic Ind front fenders on my sons 69 Chevelle. The passenger door is aftermarket sold by Muscle factory. The drivers door is the one that was on the car when he bought it. Both fenders meet ok at the top and bottom. The gap is ok for a driver. The alignment from the top is ok for about 6 inches and from the bottom up about about half way. The problem is where the fender has it biggest curve about 1/3 from the top. Both fenders stick out further than the door. The drivers about the thickness of the door skin, The passengers is worse. We have adjusted everything that I can think of but I'm not a body man. If we adjust one thing it throws something else off. Any help is appreciated.

This is ALWAYS a problem with after market parts. Perhaps American made are somewhat better than off shore parts but there seems to always be issues with anything other than NOS or good used OEM parts. A good body guy can rectify some of these issues but it will most times require some welding and metal work.

Ram. I know what you say is true but also a problem with used oem parts. I replaced a fender on my 71 with a used oem and the body lines were very bad. I had my original repaired and put on. The same thing happened with my sons 1975 Chevy pu. Replaced a door with a used oem and had to go back & repair the original and put it back on. I suppose our next stop is a good body shop.

One way you can attempt is to force another shim or two in between the fender and cowl at the bottom bolts. That will pull the bottom of the fender down which pulls out some of the curve. If that pulls the whole fender down too far then you have to move them to the top on the vertical bolt or bolts.

Otherwise, put a wood block against it in the middle right in front of the door and hit it with a sledge hammer. It may sound wrong, but if the curve is too much then a little force bending it straighter will remove some of the curve.

Haven't tried the bottom shim yet and definitely haven't tried the sledge approach but will give both a shot. Tried the top shim and it did not do anything. Told my son I had to align the trunk on my 71 by putting a 2 x 4 under one corner and sitting on the other to tweak it.

If the top of the fender lines up with the top of the door and the door has the proper gap at the rocker, shimming the bottom of the fender should work. As stated, it will pull the middle of the fender inward. Keep in mind that even from the factory cars of this vintage did not fit perfectly and they may have even left the fender out a bit for door swing clearance and cut wind noise.

Some days it's not worth chewing through the restraints.
