What you say makes sense. I suppose my next step will be to see if I could source the SS links that attach to leather strap to the case. I was looking at a 5726 today and the case dimensions and lug dimensions are the same as on the 5980, so the strap and link combo used on the 5726 should work for the 5980.
Whit, would you mind posting some pics of the pins ? I'd just like to get as much info as I can before in start hammering away
