Torque shaft/clutch fork

[dodge68charger]

I have a few different torque shafts and clutch forks in my parts bin. Is there reference numbers on them or measurements that i can use to make sure im putting the right one in my 68 b body big block car. I really dont want to buy new ones if i dont have to. Thanks

My suggestion would be to go to "Brewers Performance" online catalog and see if their pictures will identify the torque shaft that is correct.......................MO
