to all by the subject title you might guess my problem.
doors that are very hard to open.

Last winter I had my car up on stands while I totally redid the 
suspension front and back.  When I did the rear suspension I placed the
stands well back of the rear wheels so I had elbow room.  When I did the
front, they where placed about the rear of the engine.  

Gee if I had only known!!!!!

Okay now what do I do so the bloody doors open normally or the frame is 
is reset.  take it to a body shop who will put it on one of 
those stands and . . . . . . . (ugh)

thanks
