When you get your new part just for grins measure the distance between the claw and the anchor lug and see if your old one has gotten wider than the new one. Back in the 70s and early 80s the market had a bunch of import arms with parts that would bend or stretch after a few hundred rounds.
I will get the dial caliper out later tonight when the household calms down a bit. That would be an interesting comparison.
Thanks for your input.
Edit: I couldn't wait had to know, 0.455" on both parts the new and the old.
