I picked up a 1977 G20 with rally rims, but it was missing hubcaps and beauty rims. I picked up some used hubcaps off ebay, but can't figure out the best way to attach them to the rims.
Looking for answers, thanks

If its the hubcaps I am thinking of, they are held in place by tabs that snug up against the lug nuts. Some have a small 1/4 inch bolt that goes from the back of the rim to fasten the hub.
