Rear bushing question

[Loulang]

Has any one used prothane bushings for the rear leaf springs and shackles? I’m wondering is there is a grease I should put on these when I install them. If so what kind. Thanks in advance

Make sure you can use those with stock shackle pieces. Otherwise you'll have to find or make something. Alà 70s jacker uppers.
It's the sleeve being the issue.
Stock rubber works perfectly fine.
Silicone grease.
