Stereo Mod for a MV-1B?

Ive seen it done for a 1-C, and its seems very simple. But I know that the 1-B's boards have different trace posistions and numbers. Has anyone done this/provide me with the knowhow to perform this mod? Id appreciate it greatly. Thanks!

MV-1FZ Thread

The thread initally is about the MV-1FZ but a little ways down, it has info on the MV-1B with some great pictures from MKL. I used this info to do a stereo mod on my MV-1AX. Good Luck.
