70 dart 470 ci drag car build.

So yesterday I figured something out when everything lined up and measured the same except the frame rails distance to the quarter panel.
I totally forgot about offset Chrysler put into the car, so I have to remeasure that and or just be okay with 18 on the passenger side and 19 on the driver side.
When I measured the stuff last Sunday I had 18ish on both sides.
Anyways I don't really need a delay
