Hi Dbrittss1917, And thanks to all the forum members who have expressed confidence in me over the years! It is a very special group here, and I have a lot of respect fo my fellow members.
As for the broken middle link, I think either the part was improperly heat treated, or, a flaw in the metal? I've never seen one break in that spot? But, being that you're replacing it, make sure you have the headspace checked, or you might just go from bad to worse??? :

Best of luck with your repair, til.....lat'r....GT
