M38 cowl battery box lid

What is the proper connector under the cowl for the wing bolt
that holds the cowl box lid on?

I have looked at Wes' tub photos but may have overlooked it.

Babaloo scrapped out the original holes both in the lid and cowl,
Drilled some new holes inboard of the originals and welded washers
under the cowl.

Oh, and smoothed the disaster with Bondo.

Of course.

They are actually called Stud, wing type round head or zeus or camloc fasteners. The latching receptacle for the studs is fastened to the lower side of the hole. You can see these receptacles in this full size version of my cowl box photo:

Wes,
I apologize. That box is sitting in my garage, and although
I separated the lid and portion of the cowl to work on the box,
completely forgot the cowl portion extended far enough to
include the latching receptacles on each end.

I can take a couple of photos of the inverted lid/cowl
with the latching receptacles if anyone in interested.

Thanks,
Brian

Of all the mechanical quarter turn fasteners produced over the years, Camloc, DZUS, and AirLoc were the leaders in the market. The type used in the M38 cowl box are probably old style AirLoc's.

The old style AirLocs remained very simple with a plane stud, cross pin and receptacle. They seldom included any type of spring. The spring type retention was a feature of their receptacle. Their weak point was the need to remove and install the cross pin to get the stud into and out of the panel. This wore down the larger diameter splined center on the cross pins and they would then slip out in use.

This is the cross pin tool for them:

Ok, those are pretty, Wes.

Are they available ?

I suspect the bending of the receptacle along with compressing
the lid seal provided enough spring to keep them tight.

As they used to say in the old Telephone Yellow Pages ads: "Let your fingers do the walking" and google Airlocs and shop for a good price!

A quick search shows Airloc must have let their
Trademark lapse as there is a speaker wire
termination with that name filling up the search lists.

Digging deeper...

This appears to be a suitable replacement:

I will need only two.

Anyone interested in a couple or more?
