T-5 transmission

[marko]

Have a ford f1 1950 w/T-5 transmission.

Everything was shifting fine for the last 3 summers. Today, after shifting into 4th gear I went to put it into 5th gear and the best way to describe it is.. the shifter arm had a lot of play.. couldn't find 5th. In fact I can't find any gears. it just moves all over the place.

where do I start? the clutch works just find. press it down and it engages, just can't find any gears.... HELP
