Broken LCA pivot mount!!

I've got a jig that has a pair of pivot pins welded in the correct location so that when I had to fix my son's k-member last year there was no issue. The tube is also not straight. One end is tapered down so that the pin fits tightly. Somebody had "fixed" this before, but the pin was never able to get tight due to the extra metal they added. I usually cut a hole in the k-member so that I can reinforce it from the inside. The original welds were insignificant...Last pic is typical of the one end.
