I needed a strap for my 00 tin. Couldn't find any 3/4", aka 20mm flat hooks for the strap, so I purchased some ss 1 inchers. Had to file down the sides to make it fit in the slot. You can see where I ground on the left hook. I kind of ground down the rounded strap slot, but all went well: Purchased some 1" elastic webbing, and had the wife sew it for me. Here's the result: Instead of sewing a hook on each end, I had her make a loop, for a little more strength: She stitched a square with an x in the middle. Very happy how it turned out. I had some 1" olive drab webbing, and tried different buckles, but it turns out that the buckles for 1" webbing are just too darn big for it, so I went the elastic route.
