Brazilian Dodge Dart 76 (similar to 69 usa)

well... people tell we have to weld subframes with car on 4.. suspension 'loaded'.
front end of the car is ok.. they are leveled on ramps.
rear end... I will use 2 lifters under the rear springs.. will lift car slowly... level it.. and quickly weld.
That´s my plan. Probably will work :P
