Anyone know if a 72 Duster K member will fit in a 74

Yes, it can be welded up. I've fixed worse. I do this on the side, as well. Every k-member I do spends a day or two in my hot tank before I start work on it. I also have a jig that keeps the pivot pin tubes in the right place. Here's worse...

Somebody had already "fixed" this one, but the pivot pin would not go tight on the one side due to the plate they welded on. So, it came apart. One of the things that I do is to cut open the lower half below the tubes so that I can weld them in from the inside. Last pic is one that I worked on that didn't have any breakage. This is just to show how pitiful they were originally built...That k-member was twisted, BAD. Yes, I straightened it...
