Starting on the drivers side D1 will be the front straight door, just measure the full width of the door.
D2 will be in front of the front wheel, if there is a wheel flare we will need to measure from the left edge to the point where the wheel flare begins. If the flare starts above where the stainless will be we can make it a full width panel so you will measure the full width from the left edge to the right edge.
D3 will be behind the front wheel, measure the same as D2.
D4-D8 are straight doors, measure the full width.
D9-D10 are in front of and behind the rear wheels, if it is flat enough, measure the full width. If there is a flare that will interfere then measure up to the flare.
D11 will go under the radiator area, we will need dimensions A through G as shown in the drawing below.
D12 we need A, B, and C as shown below.
P1 goes to the left of the entry steps, measure from the step opening to either the wheel flare or the edge depending on if the flare interferes or not.
P2 is behind the front wheel, measure the same as you did on the driver side
P3-P6 are straight doors.
P7-P8 are on either side of the rear wheels, measure the same as you did on the driver side.
If the remaining panels are straight you can just measure the length, if they have an angle along the bottom we will need measurements A, B, and C as shown in the D12 drawing above.
