clutch engages high after t-3650 swap

I recently finished the auto to manual swap in my 96 using a t-3650.The problem is the clutch seems to be engaging when the pedal is too far up. Im using the stock setup including the self adjusting quadrant. It seems that the cable doesnt have any/enough slack in it.The trans is out of an 2002 or2003.According to autozone the clutch cable is the same part number for 96-04

would a firewall adjuster add some slack to the stock cable?
