I have a partial solution to your excessive cable length. FOund a 92 mustang in the junkyard with a 5 speed still in it. Going back tomorrow to grab the transmission. However. The cable should route out the firewall and over and loop the drivers engine mount and then back to the mount on the transmission. guess they want the cable to have a long bend instead of a tight one. Once I get the trans out - I'll take a picture of the swivel bracket that mounts on the transmission further back from the clutch fork.
