Running Board Problems 31 Dlx Roadster

[Big hammer]

It looks like the running board needs to move in towards the apron.
If all bolts are still loose push it towards the apron. The key hole slot
in the running board is for installing cone head shaped bolt and sum
adjustment like where you bolt RB and fenders. I have used long nosed
vise grip pliers to hold cone shaped bolt from turning when it's to close
to the rounded hole of the key hole. Hope this helps can be a real pain
