I hear there are some newer replacement-type shackles that might be better, but I'm not sure what would work best. I hear urethane bushings squeak just as bad or worse. These nylon ones from Speedway seem highly rated, but I'm not sure what's best.

I used the Speedway shackles with urethane bushings and they didn't last very long. I replaced the bushings with oilite bronze bushings.
There is a lot of horizontal pressure on those bushings as well as the weight of the car.
