Yup as I thought. It’s how mine isI believe that stud is a metal screw and does not have a nut. Check out the Rootes Sunbeam Alpine Parts List. (I am looking at the Rootes Archieve Trust reprint of Publication Number 6600992, 1966.) On page YX30, about 1/4 of the way down the page, you will see two lines whih read:
G378 9128011 Stud-Hood to body side 2
G379 9128012 Stud-Hood to body rear 2

The "G" refers to Plate G - SECTION YX. Stud 378 (side stud) is shown on the top line and you can see the bottom of it is NOT threaded to receive a nut, but to screw INTO sheet metal. Stud 379 (rear stud) is shown on the bottom row. Again, you can see the bottom of it is NOT threaded to receive a nut, but to screw INTO sheet metal. So you don't have to worry about getting to the underside of the stud nor the sheet metal - unless some previous owner put in a stud requiring a nut.

Good luck!

Probably why it was a screw in peg originallywould be easier than taking the trim off and attaching a tiny nut out of sight in a narrow space with my gigantic hands
originally these were just screw thread (sheet metal screw) with no nut. after 50 years of pulling the top or tonneau cover over them they get loose and wobble. They are also offered in machine thread (#10-32) and I have started fitting them. access to the inside of the cavity can be achieved by removing the upholstered panel (casing). the nut will either be a small pattern #10 nut which is 5/16 AF or a 3/8 AF which is a standard #10 nut. I use either a nut driver, or a 1/4 drive socket, 2" extender and a ratchet...Ok guys How do I get to the bottom of the front peg . It’s threaded and the securing nut has vibrated off . Although the peg looks ok it’s just sitting there View attachment 19792
I usually use a serrated lockwasher...I would also like to suggest that a drop of the non-hardening Locktite be applied to the threads, to help prevent the nut from vibrating loose.
I use the external tab serrated lock washers.I usually use a serrated lockwasher...
If it is a metal screw type stud that has stripped out, you can replace it with an 8-32 type stud and access behind the interior fabric panel to install the nut & lock washer. A more elaborate install would be to replace it all from the top with a drilled in 8-32 riv-nut.Ok guys How do I get to the bottom of the front peg .
