What type/brand sway bar bushings are you using?

Looking to install new front sway bar bushings in a 70 A-Body and I wanted to see what brand the community is using. I'm told the originals had a recessed/trough built into the rubber bushing to allow the grease to retain. I was told the polyurethane bushings may squeak over time. I wanted to reach out for professional advice before making a mistake.

I use poly through out the suspensions in all my builds/customers for the last 2 or more decades, ZERO squeaks if installed and lubricated properly

I looked but couldn't find anyone that made rubber replacements so I had to go with the poly version
