Sub-frame connectors... Please build them correctly!

I installed mine upside down on a rotisserie on my Dart. Hope I can get doors to fit after I weld the roll cage in.
I think I rotated it right side up and supported by jack stands before connecting front to rear. Can't remember, we will see.
Anything is better than nothing. Your choice of what you want and can afford. My Duster flexes like mad on the track without any.
