In the process of re-restoring my 67 conv and looking at the brake lines available today I see color coded fittings for use around the master cylinder.
Back in the 80's I used GM bulk steel brake lines plus armor and reused the original master cylinder fittings because they were in excellent shape at that time but I never recall seeing colors on the different sizes.
I checked my survivor and they are also in good shape and show no signs of color. Is that something new today and if so, is it acceptable for judging?

Thank you,
Mike

I wouldn't get too worked-up over minor stamping variations; Delco made those distributors at 1600 per hour (one every two seconds) spread across several lines.

Hi John,
 Was this a random daily occurrence or scheduled batch runs based on inventory levels and rate of consumption?

Mike

 Not sure for '69 then. I checked my 67 BB's and for the engine assy date of T0214 has the dist dated Jan 6th '67. My T0308 engine distributor is Feb 5th '67. Seems about a month lag for shelf time.
Interesting now that I see this how both were made the begining of each month. I wonder if that is when a batch run was scheduled?  
 
Mike

 The distributor date should be before the engine build date, not the body.

I still have the original clamp on my 67 4B LOS survivor (w/dimples) and it has several traces of black paint. It also has the K stamped into the one side like yours.

Mike

I ran a metal line back in my racing days and the only thing I found annoying was it telegraphed engine noises into the passenger compartment.

Hi Brian K. here, I took a quick measurement of the firewall to engine block line and it's about 7 inches long. I dont have access to my inside line but the Chevrolet service bullentin says that dealers are to take off the junction, drill the hole bigger (1/2 inch in size) use the line thats inside the car to go to the block (it supposed to be long enough) and add the rubber grommet part number 3906193. Remember this is for people bringing their cars back to the dealer with oil leaks, that how GM told the dealer to fix it. The bullentin says effective June 5, 1967 the 2 piece design will be replaced to this one piece set up in production cars. My 11E build 67 RSSS has this set up owned since 1988, my original lines are white translucet in color. The current repops are black, I've found a good replacement from Auto Meter part number 990023 which looks and functions like original. Glad to help, I'm using my dads account here sorry for any confusion. Sincerely Brian Kotula

The bulletin may have listed June 5th but that is likely for the cars with the brass fitting installed before the redesign mentioned as 3/10/67 in the AM. I would suspect after that date the oil line was a single unit and used a grommet and the service bulletin released afterwards when failures started to show in the field. The AM drawing release date showing only the grommet was 4-15-67. So I would say Bob that your 5E likely came with the oil line and grommet. What size is the hole in your firewall? That should give an idea of what you should be using.

Mike

I found the fitting and attached 2 pictures showing the body and the oil line compression method.
I removed this from a Dec 66 Camaro w/gauges parts car in '82 (not 87 like I said before). Notice there is a nut in the middle of the fitting to snug it to the firewall.

My 67 5B NOR car has the grommet and a single oil line. Looking at U17/A3 & A4 I see "Redrawn & redesigned" 3-10-67 and just show the grommet so I wonder if they eliminated the brass fitting if it did exist

Mike

 Anyone with the brass fitting have pictures to post?
I'm looking for one I pulled from a car 25 years ago to take a picture of.
I'll post it when I find it so we can compare.

Mike

Mike,
Just wondering, do your 67's have a brass fitting or a rubber grommet for the oil line at the firewall?
Bob

Hi Bob,

  It's a grommet. I do have a brass one that I pulled from a parts car back in '87 that was screwed thru the firewall and the oil line was 2 pieces. I heard here that was never factory fitting but I dispute it because I have heard other people with the same setup in earlier Camaros. The car I removed this from was Dec 66 SS350 if I remember right.


Mike

Hi Marty,

 I would say it depends on what alternator was used and how many in a batch run. The standard alternator with a car ordered with little options that required anything beyond 37A would be consumed faster hence closer to the vehicle assembly date than one that was used with let's say A/C.  So maybe a week before to several weeks depening on the demands.
  Like the gas tank date vs. cowl date thread, maybe one for alternators?

Mike

Hi John,

  Not to deviate from the main topic but I've seen this photo a number of times and each time I study it I notice something new.
I see the 6 cyl engines are blue. Was there any significant reason for that color and not Chevy orange?

 I see a very familiar thing though with the floor. It looks like it is built with wood blocks, no doubt due to the weight of the engines and the machines moving them. When I worked at Grumman Aerospace years ago several of the older assembly plants that were building aircraft during WW2 and beyond had wood floors made with 10x10 blocks (if I have the size correct) stacked tightly side by side.

Thanks,
Mike

When I had the car it already had the cowl hood. Car was a very nice driver quality restoration. For a pic of trim tag go here.

Wow...that does look really nice as is in those pictures. So, the firewall markings weren't on it when you had the car I assume.

Mike

 Are you sure of that Daniel?
  Some engines were built and sat on a rack for weeks to months before being installed in a car. So in this case for alternators that were installed during engine dressing, the date stamped may very well come before or after the engine build date depending on the volume and popularity of parts consumed on the assembly line.
In the case of my 2 '67's with originl electrical parts the LOS built car has the optional alternator so it sat for a while and was built before the engine assembly date before being installed.
The NOR car used the standard 37A unit so the build date was more recent relative to the cowl assembly date but after the engine build date.
LOS- Engine date - T0214 - Cowl date - 4B (UOIT lists 4/13/67 specifically)- Alternator date 7A30 (optional 1100696 - 42A) - Voltage  regulator date 7C
NOR - Engine date T0308 - Cowl date - 5B - Alternator date 7E4 (standard 1100693 -37A) - voltge regulator date - 7E

Or did you mean engine build = engine dressing?

Mike

I just ask for pics of TT and block stamp. I also mentioned M21 on window sticker which is obviously a fake and the ad said M22. See what kind of fire that lit.

Was there any reply to this request yet?

Mike
