'40 Ford Tudor chop. The rear cut goes from the corner of the 1/4 window down to the bumper slot. The chop height comes out of the pan below the trunk lid. Do not cut across anywhere on top. You don't lengthen the top at all. This way there is no chance of ruining the graceful curve of the top's profile. The top doesn't need to be lengthened because you let it move forward to line up with the windshield posts and the work is all in the lower pan under the trunk lid.
