rear tires not centered in body

I used for side to side. Found the center of the axle. The rear side. the opposite of the pinion. I measured from the inside of the frame rails to the tape that has the mark for the center mark. For the rearward measurement I did the spring perch back to the axle. The axle was on the springs clamping bolt. There is not much room to move the axle.

I will have to re-measure the spring perches. I may have measures from outside to outside of the perch. As I said the axle was not modified when I got it. If it was it was an excellent job, just as it came from the factory.

I will post pictures later today of the axle and the tolerances of the fenders.
