p.s. the only 24 volt factory-built planes were the L-5G models. Post war, circa 1947-1951, the Navy and Air Force converted most of their earlier L-5’s to the 24 volt standard they adopted for all of their aircraft. It appears that 03971 was converted at Cherry Point in 1948 and the record card was changed to reflect the OY-2 conversion in 1949.

Wes,
Sam Taber hides his ELT and Com antenna inside the vertical stab. The wood / fabric doesn’t attenuate the signal and they are completely out of sight. If Sam doesn’t reply here, give him a shout.
p.s. Aircraft Spruce carries the Mil Spec #2 flush Airloc in only .051-.060″ and .171-.180 grip length. Look under their A-spec fasteners.
Depends on which size(s) you need. Some are available and some are not. For a long time AVICO was the go-to source, but they no longer exist. Another source is Mil Spec in Florida, but they have a limited selection. About six years ago the CAF High Sierra Wing looked into getting the uncommon lengths made and at that time Mil Spec required a 100-piece minimum order in any given size. I never heard what came of that inquiry, but High Sierra no longer has their L-5.
As an alternative, Skybolt Aerospace Fasteners makes their ALoc fasteners which are Airlock compatible. I have not yet figured out which of their stud numbers corresponds with the original Airlock numbers (another “on my to-do list”), but their website has a short video showing how to measure them. See https://skybolt.com/portfolio/aloc-aircraft-series/. If you take this approach, let us know what transpires.

1. Those clips are a commonly missing item. I might have some spares, but won’t be back in AZ to look until October or November. If you still haven’t found any by then, remind.
2. You may have noticed that the drawing the cross references some 77- part numbers. Those refer to the Stinson V-77 / SR-10, so if you can’t find any through our L-5 group, try the International Stinson Club forum at https://stinsonowners.org/.
3. In case you are unaware, all the L-5 drawings are also available through the club, they’re just not accessible online to everyone yet (maybe this winter’s project).
4. If you strike out finding the mounting clips, they wouldn’t be too awfully hard to make. As you can see, use 0.051″ (16 gauge) 24SO soft aluminum and then heat treat. If you cannot find a small piece of 24SO, you can easily come by the tempered 24ST variety. Just anneal it to remove the temper, work it to shape, and then heat treat. Sam Taber (Tabair) has a heat treating oven but there’s probably a local shop near you that does heat treating. Of course, if you end up making two, you might as well make twenty.
