Overdrive 4 speed linkage

I have one, but If I remember right, 65Cuda273 also tried one and ended up sending it back. So, I'm afraid to try it yet. One day, I'll have time to try all my ideas. I'll try the next clutch when I swap O/D transmissions. I got one from Australia I'm itching to try. I have gone back to the 10 in factory clutch in the 66 but it is slipping in 4th already. Should have just got one from Brewers like you did. I like the factory linkage and the way it feels when right, so will probably never go to hydraulic throw out.
