Towing a 68 on car dolly

What I meant was No it's not easy
cuz you have to take the chunk right out, probably an hour and a half in your driveway plus the time to pop the spiders out and replace the pin. And now you have the situation where the sidegears are constantly spinning in the case and the pinion/RG, not spinning, and those parts are not engineered to run that way. I have no idea how that would play put, but I suspect it wouldn't be good
