ticking from tranny when clutch is depressed

[snailed]

I swapped a 90 transmission and transfercase into my 92 talon but put the release arm from the 92 on the 90 becasue it was new, now when ever I depress the clutch I hear a ticking sound from the bellhousing which varies in speed with the RPM. coulde it be that the 92 arm is longer than the 90 arm? I don't know what is going on.

i would look into it being a throw out bearing.
