Clutch linkage problems

[63chevy4x4]

I have been working the past few weeks on putting an engine in my 63 4x4. I put an engine and bell housing in the was in a 62 chevy 4x4, the only diffrence is the 63 has a 4 speed and the 62 had a 3 speed. My problem is when i put the clutch pedel down the throwout bearing dosent even touch the clutch fingers till the last half inch. The clutch is in the right way and hasnt been apart since i ran it in the other pickup. The only thing I can think of is that the linkages are diffrent from one cab to another?
