'39 Chevy 2dr Sedan

As I just explained the trunk lid should measure 39mm and that's just what the delivery rear door measures. The problem is that the sides (where the taillights are mounted) is halfway between the fender welting and the trunk lid. The delivery is almost out to the fender welting

You can see how the body is too wide. I'll cut out about 5mm on each side. I figure the body measures 10mm from the door opening to the fender welting. It needs to be midway, so that means removing 5mm.

The crosshatched area will be removed.

The roof cut. The dashed line was plotted through the tape grid from the reference photo overlay. Note: You can get FREE photo software at www.gimp.org

This was very difficult to explain but these two pictures are worth the proverbial thousand words.

Just squeeze !
