Trunion and ball

I have a 65 barracuda automatic with ball and trunion. What valve body would Interchange with it? Also it possible the trunion to be making like a rattle noise? Only when getting and off the gas. Also always thanks in advance for any help

The ball and trunnion has sets of needle bearings in there (the ball part) might allow for some play if they are worn. Double check the torque and play on those I would think. They have rebuild kits but you have to be very careful with the pin etc, to keep proper balance.

Anyone else have thoughts here?
