In your first photo, rather than having a smooth curved edge along the outside edge of the running board, it appears that the front portion of the running board (where it turns down towards the ground) is flared outward away from the natural curve of the board. This might be an optical illusion caused by the camera so I could be mistaken. Attached are some photos that may help. Keep in mind that on this 40 the front end sheet metal sits very low with the inner fender panels resting on the top of the frame rails. This is not OEM correct and makes the front end look lower. plus the car has 15 in. tires and a 4 in. dropped axle. The 1st photo shows the measurement with the tape measure hooked onto the inner bottom lip of the frame rail to the outer lip of the DRAKE running board cover. Photos 2 and 3 show the measurement from the lower corner of the running board to the rear of the fender opening. Maybe you can compare these measurements with yours as a starter. Of course getting these measurements off a stock 40 would be even better. Just wondering if you are having the same problem with the both boards. Follow Mike's advice and you will be fine, I think. Oh, one more thought. Does anything change when you remove the inner fender splash apron?
