Thanks for posting. That 54970 is a very common shank. I have an older one from 2004 in the shed. I'll look tonight if a lot number even exists on it. I also happened to see the country of origin in the kit page in the recall. Not good.
That shank was also "up-rated" a few years ago from 1,200# to 1,500# with no apparent outside looks. Do not know if they actually changed the way the shank was made or the test they used to test it with. Or if it was built heavier and the sticker de-rated it since until a few years ago Rees never offered anything above 1,200”# WD bars. So why offer a 1,500# shank.
