Sorry to interrupt your lively internet discussion. But I would like a few items clarified, if either one of you or someone else could please help me in the right direction as far as finish on several pieces of under car parts. First off the backing plates on the rearend black like the housing or natural? The center section same? The nuts that hold the center in, natural or correct finish? The lower control arms? Upper A arms? Front sway bar? Any help would be greatly appreciated.
