Never jack the rear of your rear wheel drive car up with your floorjack without blocking your front tires first. Especially if your driveway has a steep incline. Stopping your car from rolling down hill is not an easy thing to do. It will stop real quick when it hits the car that just so happens to be driving down your street at just the right time. This tends to be costly and most likely you'll need a new floor jack!

 

guess you don't want to tell us how you know all this do you?

 

i remember a 1969 galaxy500 i had, drive had a bit of an incline and i parked it and it somehow popped out of park and back itself into a tree and tore the back end all up, a lil scratch for the tree damage...

finding parts for an year 69 car is impossible...
