Use old .... " Stainless Steel Spring Bar Sleeve's ".
If at all you can not find them, I use ( Old Spring Bar Tubes) and make (Stainless Steel Pin's myself.
Find the (Spring Bar Sleeve) that fits and press them in to the link. Then just shear or cut them off.
Hard ware stores sell " Stainless Steel Pins and Wire materials ". Cut or shear them off to size.
It works fine for me and still be like the originals.
