Deceided to share the detailes of a accident i had last tuesday.I had a 56 Ford Wagon jacked up in the front with oak blocks 10" x 10" x 24" under the front wheels.I was taking the trans. out and getting everthing under the car ready to pull the engine.I didnt have the rear end off the floor and i had blocks behind the rear wheels so it wouldnt roll backwards.I didnt block the front of the rear wheels because i didnt see anyway it could roll forward,but guess what it did roll forward.I didnt get out in time and the passenger side tire landed on my legs.My garage is about 100 feet from the house and it took about 10 min of yelling before i got my wifes attention.10 min can be a long time! Am really glad i had taught her how to use a floor jack. Dont know how but didnt break anything but i am really sore and black and blue.You can bet i will block both sides of the wheels next time(that is if the wife lets me back in the garage Also forgot to mention the emergency brake didnt work Thats my story   Carl Lynn
