Thanks for your comments Tim. I have sent an e-mail to a local company that specializes in galvanizing (http://www.kornsgalvanizing.com/). I'll let you know what they say.

Has anyone ever had their fuel tank galvanized 50% Tin/50% Zinc)? I have an extremely clean original date coded tank that I'd like to bring back to a factory looking appearance and do not want to paint it. I realize the original tanks were Tern (20% Tin/80% Lead) coated and this formulation has long since been stopped due to the hazards of lead.

Thanks,

Bob

Many thanks to all who have contributed to this thread. I never thought it would have turned out the way it did. I was just looking for an answer that I thought would be easy to provide................if you have a manual that lists it!,  Grin Grin Grin

Thanks again!

Well how about that! I thought I was the only one that was missing that section.  Grin

Thanks for the '69 section 5. I'll keep it with my '68 Service Manual and until someone else comes up with section 5 for the '68 version.

Thanks again!

Many thanks Pete and Gary. Mystery solved!

For what it's worth, attached are 3 consecutive pages of the '68 manual which shows the omission of section 5.
36  Camaro Research Group Discussion / Originality / Re: Rear Brake Standard Diameter on: February 11, 2014, 01:11:41 PM
Thanks. I did notice that manual states that it could be bored 0.060" over (attached picture) but no reference to what the standard dimension is.

What I have now just discovered is that there is no section 5 in the Specifications section of the '68 Service manual. If goes from Section 4 (Rear Axle) to Section 6 (Engine)! Maybe that's why I couldn't find the standard dimension!   Grin
37  Camaro Research Group Discussion / Originality / Re: Rear Brake Standard Diameter on: February 11, 2014, 11:33:07 AM
Yep. That was one of the first places I looked but came up empty handed there as well. Perhaps I'll give my local Midas shop a call to see if their DB goes back that far.
38  Camaro Research Group Discussion / Originality / Re: Rear Brake Standard Diameter on: February 11, 2014, 10:22:25 AM
Gary, yes, that is exactly want I'm after. Couldn't find it in the '68 Service manual but maybe it's listed in another manual??

Thanks!

For what it's worth, I found the article below which states that the maximum allowable inner diameter of the drum was not cast into the drum until 1971. Don't know whether or not this is true.

Thanks Gary. I am indeed referring to the drum not the wheel cylinder. I too, thought that the maximum rebore diameter would also be on the drum but unless I'm totally missing it, it's not on the drum. The only thing I've found is a part number and a (casting date?) code. See pics below.

Thanks,

Bob
41  Camaro Research Group Discussion / Originality / Rear Brake Standard Diameter on: February 10, 2014, 09:23:05 PM
Does anyone know what the standard (inside) diameter of a '68 rear brake drum is? The Service manual states that it can be rebored 0.020" over the standard bore but I could not find what dimension the standard bore is.

Thanks,

Bob
42  Camaro Research Group Discussion / Decoding/Numbers / Re: '68 SS Emblem with Standard Grill on: February 02, 2014, 08:25:30 AM
Thanks Darrell. Your emblem looks identical to my original (first pic below). I've always assumed that this emblem was incorrect and a reproduction since there is no casting number on it. It was mounted using the small bracket shown in the picture.

The NOS emblem I have (2nd pic), which I thought was for a 68 is p/n 3981921 with casting number 3982043. In reply 7 of this thread it was reported that this emblem is used on a 69-71 Camaro. The studs on this emblem are about 1/2 inch longer than my original and came with the larger mounting bracket. HBC sells a 68 replacement emblem, which according to their website replaces the 69-71 emblem with these numbers. So then what is the difference between the 68 and 69-71 emblems?

From a functional point of view the NOS emblem (69-71) is acceptable and will look and fit just fine but the backing plate is still a mystery.

Is your emblem mounted using the small bracket or large bracket? Also, do you know if it is the original emblem to the car?

Thanks,

Bob

Is this the part you are referring to?

I didn't find the yellow ink stampings but I did find the orange stripe on my '68 Norwood 01C car which I recreated during the subframe restoration.

I also have a '68 396/325 with AT. I purchased my carb from Custom Rebuilt Carbs (http://www.customrebuiltcarbs.com) a few years ago. Not cheap but it is correct correct in every way right down to the date code. Ask for Phil. A very nice and knowledgable guy.

Good luck!

Bob
