Will 68 727 valve body plate work in a 85

I agree with Kim. I doubt it'll work. Many changes to the VB between those yrs. As long as the 85 isn't a lockup you should be able to use the entire 68 VB in it. Just won't have PT kickdown but I've heard Torqueflitepatty sells a PT kit on e-bay so you can add it to an older vb
