Carb Chromating
 

I feel pretty comfortable as well with my research on carb Chromating. I can do the lighter yellows all the way to the darker greens i commonly see on say 66 or 67 Chevelle BB carbs.

In the spirt of making sure this info doesnt die, PM and I will gladly share how to do it, including materials.

Drove past your place the other day Rick.
You had the Chevelle out on the rotisserie and looked like you were prepping for something, so I didn't wanna stop and impede your progress.
I always like hearing the updates on the car.

NOS Sheetmetal and what to know before buying
 

So I think i have said before NOS sheetmetal doesnt always mean your getting something new and perfect. In many cases as i have been told numerous parts that never meet production standards were sent to the parts counter.

The passenger side fender i sourced clearly was an NOS over the counter part as noted in the first picture from where a gm sticker once was.

The main brace on the upper side of the fender that you see in the engine bay was installed more than a 1/4 inch off location. The nut for the front valence panel was so far off you couldnt get a screw in the hole.

In the second picture you can see the before and after i pulled the spot welds and moved things around. Even the location pin holes were either ignored or not noticed.

Clean new sheetmetal is great, but there always seems to be something you need to fix to make it right.

I bought all new GM sheet metal for my Camaro back in the '80s and none of it fit correctly. It didn't take a huge amount of work to get it to fit, but it certainly didn't work right out of the box.

How did you determine the driveshaft paint markings shown in post 276?

Based on what I can find, see in other examples and read on the Chevellestuff website pretty much all 4 spd big block cars should have the same length driveshaft and thus the same colors. I have seen a few exmaples of other baltimore restorations where the Orange, Blue and Yellow are found. I really wasnt so much concerned about being perfectly correct, as I was more about having something on the driveshaft vs nothing.

I agree with your assessment based on build sheets on line showing BY in box 19 for manual BB cars. The orange I guess is an additional balance or inspection mark. Getting ready to redo mine (past owner did it in White Blue White for some reason) in the same colors as yours so I was checking all the most definitive original cars and restorations I could find to confirm my research. Thanks for that.

That's the method I used on my '69, but it was a KC build.
