I'm trying to determine the correct finish for the brake hose retainer clips /straps that bolt to the upper control arms on 1969 Camaros with front disc brakes (they may be the same retainers as those used for drum brake applications).  I was unable to locate specific part number(s) for them however they are shown in the AIM UPC J52 A1 Page 359. HBC sells them as flat stock in natural, unplated steel. From what I can determine originals were either phosphated or natural steel. Not painted and not bright plated. From the few examples I have come across they are rarely (badly) rusted which is why I question whether they were installed as untreated. The control arm attaching bolt was zinc manganese phosphated.  Would appreciate your input.

When I inspected mine, I concluded they were most likely plated, so had them re-plated.  Note - they have a date code stamp on the clips, so if you go with reproductions, they are probably missing the date code stamp.   Note the "C" on the clip in the image below. 

I'll dig up a pre-platting image tonight.

Thanks Hans. The photo I posted was just a stock photo however I didn't note a date code on my original clips - will have to take another look.  I have no plans to use repops.

Lloyd - I couldn't imagine you using a reproduction clip!

Anyway, here's a pre-plating image of one of the clips.   My reasoning was that as the metal ring on the rubber brake line was plated originally, I concluded the clip probably was as well...nothing conclusive though.

And a clearer picture of the clip's date code "C".   My car was assembled 04B, so I'm assuming the "C" is for March but could be a supplier ID as well.  Not sure.

Great photos Hans, they are convincing, many thanks. Are you confident the attaching bolt was plated and not originally phosphated?

Why is the upper ball joint painted?

Yep, I know.....I've started to remove the paint of one side....mistakes happen!  But hey, at least I had them riveted in!

Thanks Lloyd.   Regarding the attaching bolt - I'd have to check.  I thought I cross-referenced the AMK catalog after I inspected it.

Lloyd - OK, the screw is PN 3958062.  Per AMK, page 116, it appears its available in both phosphate and zinc.   I re-used all the original fasteners whenever possible and inspected them as best I could for original finish.    For the most part, I had almost all of the fuel and brake line clip screws (PN 3958062's) phosphate'd but chose to have those two zinc plated.    Other than that's what I observed at the time, I don't remember why or have other references.

Here's some links from photobucket for these screws:

Hans, as you did such a good job of photographing the undisturbed underside of the hose retainer clip where the attaching bolt came in contact, did you also happen to photograph the underside of the bolt which would likely have remnants of its original finish?

I wish I had!!   Unfortunately not....I scanned all the pics I took and didn't see that one....As all the other fuel line and brake line screws were phosphate, I can't remember why I went with zinc for the brake hose screw.   My assumption is I must have tagged it that way when I bagged and tagged all the fasteners.    But I easily be wrong with my assumptions.  Wish I could be more conclusive....

On the 'C' stamp, it may well be a date code, but I recall seeing 'C' and 'O' stamped on other parts on my car, including the idler arm frame mount and the anti-sway bar lateral restraint straps.

Ok, too bad, thanks for checking Hans.
