Used a bumper jack on the right rear on a '70 Fury back in the 80's once.
It wouldn't lift the car high enough to get the tire off the ground.
I now take care to make sure all tires and brakes are kept in good driving condition.
Just in case though, I have a good
spare, small floor jack, 2 jack stands, a piece of micro lam. and a 1/2" drive socket set with breaker bar, as well as a small tool kit in all my rides, except the Shovel Head of course...
