Hope this helps.
First 3 photos show the bolts holding my 40 DeLuxe driver side running board. Photos 4, 5 and 6 show bolts holding the driver side running board to the rear fender and frame. Last photo taken from inside left rear fender well showing where running board is attached and also my rear jack plate. Insuficient room to take same photo of front. Are the trim clips you're asking about the ones that hold the small stainless "whiskers" to the louvered panels, Part #01A-2001? An old 1970's DRAKE Catalog shows "Wire Clips for trim Moldings set of 8 for $4.00. I'm sure that price is no longer valid.

However, C and G Ford Parts has those same clips:

I used stainless bolts for running boards, not OEM. The red pieces of angle iron you see are "jack plates" for raising the car without damaging the frame. They bolt thru stock holes in frame (front and back.) and make it a lot easier and safer to jack up he car.
