Like the title says, i'm looking for info on what would be the proper finishes on the hood hinges and springs. I've seen hinges in a silver finish with black springs and also some with all silver or all black. Anyone know what the factory did in '67 ?............. Thanks, Nick
It should be a black oxide looking coating. I can't remember the ecact name of it, but will post when I do. I ended up having mine plated with black zinc. Looks almost exactly correct and won't rust. Same for the springs.
Agree with Tom, had mine coated with the black oxide and then sprayed them with satin clear coat. The company who coated them said the coating is not rust proof which I believe if the factory coated them because they all rusted. Hope that helps.
Hmmm, I wonder if different plants finished them with different coatings. The reason I say this is both of the '67 GS cars I have owned didn't have a trace of black on the hinges when I bought them. They both were unrestored under the hood and they are both Flint built cars. This is why I ended up painting my springs silver to try and replicate the original look. At the recent BCA show in Brookfield, Wi. the lone '67 GS there wore silver hinges with black springs. I didn't look at the cowl tag to see where it was built but it looked like the car was restored to concours level. It was very nicely done which is what led me to ask this question.
I was remebering the Chevelles I have owned and they had the black coating as I remember and I discussed with a classic restorer before I had mine done. You could be right, I am sure there are some BCA 1967 experts and AACA experts who could clear this up. I need to check my hardtop and convertible which are not at the house right now and see if the hinges look stock and if so how are they finished.
The black 67 car has NOS hinges, they were put on 25 years ago, and need cleaned up, car has never been outside. The blue 66 has used hinges I painted with Eastwood argent silver. I was going to try Eastwood zinc Phosphate, but I thought it looked to black, they state it is for hood hinges.
Thanks for the input guys. The hinges on Bills black car is how I remember mine, but I still don't know what that silver coating is called. I'm still trying to find out why the GS at the BCA meet has black springs on it's hinges.
Nick: on my '67 GTO,I sprayed clear over bare metal after they were refurbished by SMS. I'm content with them. Archie
The bare metal/silver color is actually a grey phosphate process done on the bare metal. Other parts done with the process include the gas pedal linkage that bolts on the firewall. You could have the hinges stripped and re-phosphated, or just use a paint that gives them a similar appearance. JW once offered a restoration service for the hinges.
The hinges are coated with zinc phoshate, comes out as a medium grey color.. I may do another run of hinges this fall, I only do them in groups, because the nature of coating/plating is that you have to do a number of items, to keep the per piece cost reasonable. Last time I did them, blasting/press tightening/coating was $119 per pair. There are places out there that cut the rivets out and put new ones in, but that is silly overkill for the vast majority of hinges, I have been doing them for almost 20 years now. Seen one or two that actually had elongated holes, that could have been repaired with welding and finishing and new rivets, but that's a lot of work for a relatively easy to find part. And that outfit spray paints them.. JW
After I read Jim's post this morning I decided to go look again at what I had in the wagon, and duh, I have the grey zinc phosphate! I had not looked before my first answer last week when I said black Oxide and it appears I do have the correct coating after all. There was so much I restored and repainted black on this car I guess I had black on my mind when I wrote the first answer. Mine has the grey zinc phosphate, then coated with clear satin spray. They may be a bit brighter than original but at least they are not rusty!
Zinc phosphate, yeah that's the ticket. Thanks guys. That GS at the BCA probably is done to the owners taste.
I shot mine with a Rustoleum high zinc primer and then clear; same finish on the alternator adjusting bracket. Very close match to the original and clean coil clamp.
