i didnt do the body work on that dolly. i just used it for transportation. realistically if i had a perfect place to do it i would of did the whole panel on a laser aligning frame rack but idont work in a body shop anymore.
so what i did was i used 4 jack stands at even heights leveled the car out and i have metal 2x4 beams across the pinch welds from side to side.
none the less my doors were fine on the dolly.... the goal is to get it perfect which is VERY hard.
