Lion Fasteners/Lift strut thread count

I have a PA18A which has "Lion" fasteners on the bottom skins. I have not been able to locate any supplier that sells them. Any ideas? Also I have the Univar lift struts and can not find any reference as to what is the maximum number of threads that can show.

Thanks

The lion fasteners are the same as used on the supercub cowling. Univair sells them. Cant rememember the size though. -120 or -140 is most common.
