Dust Covers

[68l30]

??? What have you guy's been using for front spindle dust covers? I'm currently in the process of metal working the dings out of my "born with" set and have a repro set on order. I'm not sure how I feel about the bright Zinc finish on the new ones. I think it needs to be toned down some to be correct. Has anyone aged or refinished them ? I may stick with my old ones once they are straight, but I need a good back up.....Used set would be nice, but they are still going to need some work.

You can tone them down by giving them a very slight dusting in the bead blast cabinet. You could also remove the zinc finish altogether.

Great idea, My other thought was about 15 min in the tumbler...just not long enough to leave a pattern. Not sure why this bugs me, I'm the only one who will ever see it....

I just used a repop set on my Malibu I have been working on. I was doing plating anyway, so I striped off the bright zinc in phosphoric acid and had them cad plated. They are toned way down, not shiny at all.
I can shoot you a couple pic's if you want. There on the car.
Or, give them a quick dunk in the acid and rinse and inspect, repeat as need. That will dull them up a bit.
#3, strip the zinc, there will be a nice phosphoros coating on the steel, blow off with a air gun and a damp towell, force dry or hang in the sun ( you may have to go to AZ.) then treat with Rpm and leave the bare ?

Thanks Mike! I'm glad I'm not crazy in thinking these are incorrect as reproduced. I'll give it a shot and see how they turn out.

repops are not close to the nos ones - but do work.....nos ones and assembly like correct ones are bare steel.....nos ones, if u can find them are $$$ about 200 each if i recall.

big, if you do as mike suggest ref AZ.....i hang them outside my garage for you :-)

[68l30]

LOL...You may get a package in the mail. It's getting damn cold here....


I've not thrown in the towel on my original set....still picking and peening... <<GRAEMLIN_URL>>/rolleyes.gif

The nipple on the repops is too soft and too large and obviously the zinc in incorrect. Also I have found they usually do not fit for crap and will not hold so I have to put a series of dimples around the flange so they hold. Typical repop garbage.

[68l30]

Nice, I have one of the old ones almost done, I had to repress the nipple in it by estimating the size. Do they ever make anything close...???

Eddie, bare steel ? You mean galvanized correct ? You been drinking your brothers vino again <<GRAEMLIN_URL>>/dunno.gif

[camaromb]

Actually the originals are just stamped galvanized steel, you can see the crystal patterns in many low mile examples.

Hi Mark,
Do you have any pics of any from your low mile survivors? I'd like to see that as all I ever see are like what Mike says and bare steel. All the NOS ones I have are also bare steel. The definition of the dimple varies quite a bit on the originals. Some I have are very pronounced and crisp and some of them are not.

[68l30]

Love to see some pics...I've had to bow out on restoring mine. I finally got a good contour and a decent nipple and burned thru a edge during the final polish. Time to practice on the repro when they arrive. My plan is to remove the zinc, polish the steel and age them to about a 30k mi look. Thinking slow heat and a oil bath, clean old steel. Guess I may need to stretch them a bit too if the fit too loose. I think I have a die for that...Thanks for everyones input, I'll post up some pics after they arrive.

I sent some pictures to Chris of near NOS factory dust shields from a '69Z with the AI paper sticker. I can post some pics of a low mile '70 Trans Am with the plated shields, the small crystals are visible. On most of the original low mile cars the dust shields are never really seem to be rusted, maybe a bit darker grey in color compared to the surface rust colored suspension components.

Mark I think that we're talking about different parts here. You sent me pictures of some disc brake backing plates.
If I understood Steve ' request properly I was thinking he was looking for info regarding the wheel bearing dust caps that press into the front of the brake rotors which are part # 3775190.

Chris is correct......

Every one I had (none were really usable for a restored car) were bare steel. I do not recall ever having one in galvanized metal.

[enio45]

mikeeee - i have had about 6 nos ones and they are all bare steel.... and i got a fresh gallon of homemade vino last weekend from san diego :-)

for sure the backing plates for the front discs were galvanized - we saw that on my 1600 mile Z.....

anyhow.....hey big - - paint them white like we did in the old days!!

[68l30]

White is always a excellant day two option Eddie!


I have received the repro covers, a whopping $8 including shipping. I didn't expect much, but overall they are what they are.

First step was to remove the zinc....60 psi in the fine glass bead cabinet.

Second step, finishing the metal and prepping to finish. I was happy at this steps completion, but I wanted them aged a bit and I've still never seen them this crisp.

Final step was aging them or better yet, adding the correct patina....Day 2 if you will...Used a OA torch to heat to approx 250 degree and quenched them in oil bath. The oil never boiled, just a smooth dip. My days spent heat treating came back to me quick.

The zinc on the inside has not been disturbed and I left the bare steel under the lip.
