Browning BAR - Type 2 - 1981

I posted in the specific Browning rifle forum and didn't get very much response. Hopefully I will get some replies here...

I have a Browning BAR, Type 2, manufactured in 1981. It's chambered in 300WM. One of the action arms has broke, and I can't seem to find any place that has them. Can anyone help?
So far, I have tried contacting Browning directly, I've called Numrich, Williams Gunsight in Davison, MI (near me and an authorized Browning repair center) and Midwest GunWorks. I've checked Brownells online, ebay, and a few Facebook groups that are firearms related. No one seems to have any left or know where to get any.
The part number I'm looking for is B3176002.

If ANYONE can help... thank you!

You may have luck looking on eBay. Another option is to go to a machine shop and have the broken part repaired or made. Good luck.
