After removing the rear axle, neither the fr-1 or fr-7 fit in the forward freewheel cluster.
I am also trying to remove the bottom bracket cups for a three piece forward freewheel bottom bracket. I've done this before at the other shop I worked at. There are splines on the inside of the bottom bracket cups and they do thread out, but I can't figure out which remover tool has this 12 spline pattern.
