Restoration / Re: Upper A-arm Splash Shields
« on: June 26, 2018, 03:50:18 PM »
After reading all the posts, I was curious to how far off the set of shields I ordered from HBC are from the originals that were installed on my Z. 

What I noted:
- Thickness for reproduction shields is exact to the orgiinals, except for the dust shield by the steering column/inner fender with the bracket.  That particular shield is about 2X thicker than the others.  Fortunately, my original is in excellent shape and re-usable.
- The reproductions are glossy.   My originals are mat finish, but not sure if that's because they are nearly 50 yrs old, have road grim, and over-spray paint.  I'm wondering if it's possible to tone-down the gloss with some acetone/lacquer thinner or use a satin rubber spray paint?
- The texture isn't that far off, but the reproductions are missing the string strands.  I wonder if its possible to lay some string strands on the reproductions and add light coat of some sort of rubberized material or paint to blend them in?

Here's a image comparing the two - I'll note that the texture is a closer match than what appears in the image.

A quick scan of "The Definitive 1969 Camaro Z/28-SS396 Fact Book" published by Jerry MacNeish shows the following:

Page 11:    302 Engine.  No clip
Page 13:    302 Engine.  Both photos show clips (probably the same engine)
Page 17:    "A Clamp mounted on this bracket on early production Z/28s to contain the heater hoses.  Later production cars use a Ty-rap tin place of the clip"
Page 91:     350 Engine.  Clip
Page 91:     302 Engine.  Clip
Page 120:   302 Engine.  In conclusive.  Nov '68 built
Page 125:   396-375:  Clip
Page 125:    427:  Clip
Page 131:    396:  Clip
Page 159:    ?  Clip
Page 163:    427:  Clip
Page 181:    Clip

And a quick scan of John Hooper's book, "The 1969 Camaro Reference Book", it shows 307s, 350 Pace Car, 396 Pace Car, 302's, ZL1's, 396/L89, 427's, Original Yenko Engine compartment, all with the clip...

Net-net - appears at some point there was a change in production from Clip to Ty-rap, Per Jerry's book, but when?  My Van Nuy's April built car has the clip and had the original factory installed heater hoses, so while things can happen, would seem weird someone along the way decided to add that factory the change probably happened after April.

See AIM Page 223, under RPO C60 (AC), View B.  The clip, PN #3825416 is clearly show and there are no notes in the revision block that states that GM deleted the clip from production.   If some reason the clip was no longer needed, I would have suspected the AIM would have had a revision note stating clip had been deleted during the production year.   Granted, this is for an AC car...

I'm still searching the AIM, but so far, that's the only place I see it referenced.    Interesting, no where on Page 44 under heater hoses is the clip mentioned - not even in the revision notes stating it's been deleted.

Hmm, that appears to be the right clip, but that also looks like a more recent picture?
I don't doubt your hoses could be original, but that clip could have been added anytime before the 90's.

I went through my pics from guys BITD or buying them new (1969), and I also have seen some unrestored cars. I have seen that bracket in your last pic on early cars, but then at some point it seems they stopped using it. Not sure if it was a big block only piece at that point, most of my pics are of small blocks.

Yeah, I took the picture with a 35mm Camera back in the day and had it digitized.   I'm 99% confident the hoses are original.  70K miles on the car.  Correct "ribbing", clamps, etc.  I still have them.   The car still had the original power steering belts and many other original components.  Unfortunately, the prior owners put a smaller carb and headers on it.

Lloyd - Well, I tried a bunch of different angles, including the Dykem dyes (too dark, didn't stain well).  I called various platters, no luck.  I tried reproductions (color way off and the clips aren't even close).   Finally, I went into a Hobby/Craft store and they had Testors 1257 Translucent Blue.  Intended to paint model airplane cockpit I said, what the heck and gave it a try.    I just dusted the clips with the spray paint and found it to be visually pretty close.   So that's what I ended up doing.  Not factory correct, but optically, I'm reasonably pleased - though ideally I would have preferred a true translucent metal dye.   Let us know if you find a better option!

Here's a comparison:

All the clips, based my observations of the color after cleaning - some clear zinc, some yellow zinc, some black zinc, and finally translucent blue

Hans, Iím reasonably confident based on the evidence that my diff and the rear brake lines had never been apart or serviced and therefore assembly-line original. The blue dyed brake line clip used appears to be one of 4 variants posted here.  Is it possible the diff-specific clip (per yours) and standard in-line brake clips were interchangeably used? Would sure like to see more original examples.

Agree.  I see no reason to believe its not original, especially since the other brake line clips are original.   My best guess, based on #17 on the rear axle cutaway View C for the HD Axle drawing on page  65 of the AIM, is that for whatever reason there was a mid-year production change.  Unfortunately, in the notes block below where the #17 is referenced in the revision block, the actual date of the change is not legible.

Have you figured out yet a way to replicate the translucent blue dye on the brake line clips??

OK.  Correction!  Found a better image - how's this?  Again, these are back from 1990.  Original heater hoses.  04B Van Nuys Built.

Pretty sure all of them have the inner fender clamp, but the alternator clamps I have seen hold both hoses, and it appears in your pic to be holding only 1?

Could be but it's a figure 8 style clip.  This the best pic I have so can't be sure.

Here's the AIM section for reference - I can't make out the production date change in the notes block though

Lloyd -

I checked the '69 AIM for the rear axle, page 65.  It appears there was a production change to the clip - see note "17".    Unfortunately, the copy quality of the AIM is poor and I can't make out the date when the change happened.   I also checked the '68 AIM, but I couldn't quite make out the clip used but something definitely changed between '68 and '69 as the engineering drawings changed.

So it's very likely the clip on your rear axle is the original production clip which appears to be the same as the other translucent blue brake line clips.

Here's a picture back from 1990 of my Z/28 - it has the original heater hoses.   Note both metal clamps - on the alternator and on the inner fender.  04B Van Nuys Built.

Here's some more Lloyd -

As found during clean-up and disassembly:

Close-up of bracket before cleaning.  My assumption was it was either natural or clear zinc but it might have been painted or had overspray on it.   I went with natural for the restoration.

You can sorta see the stampings on this pic

Restored & Installed:

Lloyd -

Is this the clip you're referring to?  Note the stampings. 

I don't have an axle picture stored in Photobucket yet - I'll load some up tonight with it installed and confirm its the right clip.

The new owner has posted the car on Instagram a few times.   Goes by "mattksax" on Instagram.   Has some more pics and video of the car running.
