I have noted on early side curtains and top boots, that there are two styles of common sense eyelets used. One is the standard length, and the other is 3/16" longer. I have examples of side curtains with the longer style along the top edge of the side curtain, while the lower edge has the standard length on the same curtain. My original '13 roadster top boot has the longer style for the flaps on the sides. I wonder if that style is being used any more? Back in the mid '60s, Ken Sorensen was using the longer style. His shop made top and upholstery kits for T's long before anyone else. Also, where would you find a punch for the long ones? BTW, the width of the longer eyelet is the same as the normal style. Trivia I know, but interesting none the less.
Larry are you saying the base or foot area is bigger or the height where the fastener pokes through the material??
If the latter, one and two thickness top material fasteners, say rear rollup curtain ,bottom corners where they fasten to the tack strip, that area requires the double, the other areas where the materials only single thick, require the shorter versions.
Hopefully that's what you mean....

here's a pic....
Hope this helps.
He 's talking about 2 different eyelet (female) fasteners, one slightly longer than the other. If the opening is also a little longer and there is only one size male fastener, then the difference in size would allow a little motion when they are hooked and/or allow for a little inexactness (is that a word?) of placement, and/or faster hooking.
The common sense fastener is the same for both eyelets. Charles, thankyou for coming to my rescue!
David-
On my 1911 the two fasteners of the side of each 1/4 panel are mounted on the top of the panel. They are single height. There is a single screw in the middle of each 1/4 panel with the two MFs on each end.
The only double height fasteners are on #2 and #3 bows and the front of the backseat armrest.
