Thaty yoke is not in very good shape and is missing it's "dust boot". Can these cars be converted to a later style slip joint yoke, if so what is required? Or do I need to toss the trans and move on?

The '65 had the slip yoke, rear pump, and cable shift / cable park. I think it would be easier to take a newer 727 and adapt the pushbutton cable to work the newer shift lever?

The ball and trunnion setup is pretty darn strong and maintenance free. The boot is really about all that goes bad. Of course the resulting loss of grease would be the killer. I am using a '65 904 trans in my 360 powered '65 Dart bracket car. Still have the ball and trunnion setup. No problems even running drag radials, a bit higher stall, and Cheetah VB.

I think Imperial Service makes a kit that you can use the newer 727 work with the push buttons. I just slapped a floor shifter in mine but I want to go back to the push buttons as they are so cool.

The rest of the parts hold up fine in a 10.0 application. We'll see how the input and output shafts hold up in a low 9 second application soon. By the way the 65 tail shaft and extension housing can be either big or small block. Doug

Be very, very, wary about sending them anything, money or parts! My friend who sent them both only recently got some of his parts and money back, after waiting a loooong time, and some conversations with attorneys. He has given up on them. I suggested a 65 case, but he is going 4spd now. It takes gasoline to interest me.

We may just jump right to redoing the entire car and not worry about the current drivetrain. Just wanted to drive it a bit with the pushbutton set up, but maybe we will just pull the 318 and pushbutton trans and begin the transformation into........
