RE: WACO YMF
The linear difference top to bottom is small, but it is there. Yes the bottom is a tad longer than is the top. It has to do with the tip plate placement. If you already have one installed with the black mark down, do not cut the assembly apart. You can shape it with a sanding block and no one will ever know. It's that small.
