Strop Buckle

this is a secondary post to my original strop manufacturing a strop post. Everyone was a great help to aiding me obtained leather and canvas; i am in need of a new buckle for the strop. I do not like using rivets, and D rings. I am planning to make a 2 and 3/8 strop. So i am looking for a 2 /2/8 buckle. However there are hard to find, i would need to either part out an ebay strop, or conform to D rings. I was wondering if anybody knows were i could require them. Below i have a link to Whipped dog.com that offers a buckle i find to small for my needs.
