Shifting fork pins

[Terry/Iowa]

I'm rebuilding a shift tower and have a question for anyone that has done so before. As I reassemble I can't figure out how to get the shifting fork pins in. They are supposed to go in from inside the housing so the head will be up when the tower is bolted to the transmission and I have tried feeding them with a bent nosed needle nose and a bent nosed tweezers, but have had no luck getting them started. Is there some secret I am missing?
