Not sure how you're going to insert wire into cowl lacing.
Anyway, I have some stainless steel mechanics safety wire, and using my sheet metal thickness gauge, a #19 metal thickness is the one it will barely pass thru for a reading. The wire is plenty stiff even those its on a small drum.
If you can get it thru the lacing it will not rust and plenty stiff to bend over and stay in place.
There was a discussion on here a while ago about somebody potentially reproducing it............Jim carter ???
