Flat towing 65 Barracuda

I had a piece of light chain,, wrapped it around the back of the shaft, slide it all the way forward, and suspended it by the exhaust pipes,, saved taking the shaft out and leaking fluid, and with the chain double wrapped around the shaft,, didn't slip back..

Those heavy black shock cords would likely works as well..

Black tape around the u-joint caps,, so they didn't fall off..

hope it helps
