It was the whole shebang. The Haynes manuals for the 2.8 SOHC and DOHC cars have good sections on both 4 and 5 speed transmissions, including side-view drawings of the full setups. The linkage is really different. For example, Reverse on the 4 speed is 5th on the 5 speed. The lever layout is totally different. The rod arrangement is completely different.

It might be possible to cook something up with a 4 speed linkage and some shift rods. I thought about that, but you would have to actually mount the linkage and have the trans in the car. Anything is possible with enough time and money, but it just didn't seem to be worth it to me.
