Welcome to the Forum website.
I looked on eBay and found several active listings that I think will provide what you're seeking.
I intended to post links to click here, but found that the eBay addresses were too l-o-n-g to permit using on our Forum entry page. I've never run into this before!
Recommendation: Google eBay and use their search function near the top of the page and enter, 'Ford Y-block vibration damper'.
Hope this helps.
