The clutches made for our application by Lenco were called "Safe Drives" and did not need a whirlaway. They also had an In/Out handle so dogs weren't needed. Just a straight shaft similar to what you'd run in Cruiser with a transmission. If you have questions call David Sumek at Lenco, 619-287-2500. He's a good guy and will set you up. Used to deal with him when I was running the Blwn Alc Front Motor car.
