Disassembling steering

I am trying to remove the steering shaft/column from a
65 midget. I cannot get the coupling that connects the
long shaft to the short steering box shaft to come
off. I have attempted to spread it with a cold chisel,
heated it, etc. Does anyone have further sugestions? I
don't want to destroy it during removal as I don't see
it in Moss or VB.

Thanks,
