There is no linkage. The pedals underneath the dash actuate a clutch master cylinder over by the driver's side hood hinge area. Then there is a hydraulic line running down to a slave cylinder on the side of the bellhousing.
1984 had a oddball clutch system. It used a different flywheel, different clutch, and had a external slave cylinder for the hydraulics that actuated the throwout bearing lever. If your transmission is setup for this, you need all the correct parts to make it work.
If your transmission is a later model, then you need all the parts that match it to work. It just so happens I bought a 1984 Bronco II with a bad transmission. I had a 1986 Ranger with a good 5 speed, but it was a different model trans. But I used all the stuff out of the 1986, and it was a bolt in. I put the 1986 2.9 flywheel on the back of the 2.8, and used everything 1986 and it all fit. In the later years after 1984 they got away from the external slave and went with a internal slave built into the throwout bearing itself. So all the dimensions are different in the bellhousing and the transmission doesn't have a provision to mount the external slave.
The old manual transfer case bolted up and all the driveshafts fit with no problem. Even the transfer case shifter mounted up, the 1986 had a electric shift transfer case. I was afraid the adapter between the back of the later trans and the transfer case would not have the threaded holes for the manual shifter, since it came from a electronic shift setup, but they were there, I just had to clean the dirt out of the holes.
