TF727 inputshaft/directdrum stuck

Hi, rebuilding my first 727 (1973 model) transmission and i cant pull the inputshaft and direct drum from the outputshaft.

First and second was slipping badly before i pulled it From my car reverse and third seemed fine. Am I missing something here? Can the clutches or something weld Themself shut?

Inputshaft has some play to the sides but wont move out at all
