replacement suspension bushing advice - poly vs rubber

hey leblanc, gonna try to make Moncton this year.

again, like always thanks a lot for the advice, like kosmic and dano the components like tie rod ends, ball joints CA bushings, i'll inspect and replace worn with factory rubber but im gonna try poly for the front sway bar bushings, cab mounts, rear spring eye bushings and cross drill the bolts and add grease fittings. the old truck has been undercoated with used oil since it was new and the old rubber bushings are swelled out like mush
