So in prep to reinstall my dash and trim, I got several types of screws. And now, I am looking at the small trim piece under and around the gauges. Four of the primary ones are full open large holes, no back side with the taper to catch the oval screw. So, I ASSUME that there are suppsed to be a top hate like washer like Big John wears on his bean. I assume these would fit into the hole, then allow the screw to anchor inside......but cannot imagine what else would work. A molded trim washer does not, nor does a flat washer. Not sure what I took off as they appear to be missing now some time back. Any thoughts out there please.
