What is the correct finish on a '67 for the steering box, master cylinder, cluth arm(not sure the name, the piece that connects onto the block), and other parts like the steering column and similar pieces?

Re: Correct finish for steering box and other part
Make sure you buy the 1967 Technical Info.Manual & Judging Guide (TIM&JG), which is for sale on this website--it is an absolute necessity for anyone trying to accomplish a faithful restoration.
Your master cylinder cover should be cadmium dichromate plated, and the body should be semigloss black---sparsely applied. The clutch cross shaft will be cadmium plated. The steering box will be painted semigloss black---sparsely applied. Some power steering units are listed as "natural", which means, rusted.

Re: Correct finish for steering box and other part
I am restoring a 67 roadster right now. I bought several of the paints from Long Island Corvette and have been very pleased. For the steering box I used the cast blast which gave it a natural look. The master cylinder should be semi flat (gloss)black. Invest in Krylon 1613 semi flat black spray paint. You will use it on multiple applications. I have personally bought a bunch of it and it makes a novice like me look like a professional. I should buy stock in Krylon. Wall Mart sells it cheap!!!!!!!!!
Good luck,

Re: Correct finish for steering box and other part
I've got 2 different replies above? Which one is correct? Also I have the judging manual and it doesn't have these things in there that I can see? Also is there some way to duplicate the finish on the clutch shaft and such?Comment

Since he's quoting the TIM/JG, I'd go with Joe-BTW
Do you have the current revision 3 with the yellow pages?Comment

The steering boxes were seen both ways----painted semi-gloss black and natural. For earlier mid-years, they were mostly painted black. By 1967, they were seen both ways. Later, for C3 production (the steering boxes were pretty much the same for C2 and C3) they were mostly natural.
The clutch cross shaft can be re-plated by a competent metal finishing shop. Either cadmium or zinc will be fine. The originals were usually zinc, but some folks think they were cadmium. No matter; either finish looks about the same, especially after oxidation. If you get it replated, make sure that the plater has the knowledge and equipment to specially treat this part to avoid hydrogen embrittlement. Hydrogen embrittlement, which is a normal "by-product" of the plating process, will weaken a part. For decorative parts, this is no problem. For a part like the clutch cross-shaft which require high strength, it is a problem and must be avoided.In Appreciation of John HinckleyComment

Re: Correct finish for steering box and other part
Do you know if I clean the old paint off will it look OK? The clutch shaft I mean. Or is there another way to do it without taking it off the car? I'm taking the engine out in the winter, I just wanted a temporary solution of somthing I can do to clean things up a bit until then.Comment

The clutch shaft is not painted; it's zinc or cadmium plated. If you clean it up, it may look just fine. You may be able to do this with the part installed in the car, but it will be difficult. It's not that difficult to remove.In Appreciation of John HinckleyComment

THe problem was that when I got it, someone had painted it black. I don't know how it is supposed to look though, should it be really shiny?Comment

Re: Correct finish for steering box and other part
No, it is not shiny.
Use some paint stripper on it, then clean it up afterwards with some Simple Green. At that point, reinstall it and you'll be fine.

Re: Correct finish for steering box and other part
Factory finishes and plating are significant issues challenging restorers. Authentic representation requires careful investigation. Spray can solutions may initially appear adequate, but to the informed observer are unacceptable. A factory finish may deterioate, but will never develop a coating. Your restoration efforts may be amiss if your goals are not clear.Comment
