What about your 67 LOS. build, it has original P/S correct?
Bob
Hi Bob,
 Correct.....Original pump. Attached is a picture of it with the rubber bumper completely intact.
Julian date on P/S box is 032 7
So it looks like they were used in 67 (this picture) and up to early 69 (based on previous pictures I posted).

Hi Bob,

  When I restored my 67 ragtop in the 80's I removd the manual and installed a P/S gear box w/ rag joint from a '69 Camaro.
The Julian date on the 69 steering box is stamped 240 8
I since removed it and reinstalled the original manual steering box on the '67 but never sold the 69 yet so here is a picture of that rag joint.
It has the rubber bumpers though the upper shaft rubber has been worn away and the thick base is all that is left.
The P/N 780047X was readable except for the last digit which could be a 9 or a 0 (the rubber is nicked)
 As for the ground, my 67 manual joint uses the copper strip and never had any rubber 'bumpers'.

 I have seen the 7027211 carbs (rare to find, BTW) with dates as early as Feb 67. Your period may be at that transition period (just a guess) between the old and newer one. I'm sure GM must have depleted inventory before using the newer ones. The differences are the needle and seat design.
   Also, the linkage may be different between the 2 models. The earlier one use the larger sleeves at the carb throttle side and the 7027211 doesn't use a sleeve at the car throttle. The after market throttle linkage for the 67 BB doesn't fit the newer 211 carb correctly because the throttle side needs the large sleeves to properly fit. My 67 BB car has the 211 carb and also the 2 piece linkage that came with it when I bought the car over 30 years ago. My 67 LOS car that uses a different carb number all together also uses the 2 piece linkage.

BTW, a LOS car without AIR? I thought that was mandatory in 67 for California.

Hi Bob,

    Are you asking if the pins used rubber bumpers on Camaros?

 When I remade the lines in the 80's I paid special attention to length, shape and armor measurements and that was when I had no intentions to really show the car.
So, you are saying that there are colors (besides the gold I see on all the others fittings outside the master cylinder areas)? I'll check out In-Line Tube to see if they are exact to the originals on the master cylinder. The originals have more of a flat face to them.

Thanks,
Mike
771  Camaro Research Group Discussion / Restoration / Color coded brake end fittings on: May 05, 2012, 01:36:53 PM
 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
773  Camaro Research Group Discussion / Decoding/Numbers / Re: 1969 Z/28 cars original distributor date codes please on: May 04, 2012, 04:02:43 PM
 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?  Huh

774  Camaro Research Group Discussion / Decoding/Numbers / Re: 1969 Z/28 cars original distributor date codes please on: May 04, 2012, 03:47:55 PM
 The distributor date should be before the engine build date, not the body.

775  Camaro Research Group Discussion / Originality / Re: Original Battery Hold Down Clamp on: May 03, 2012, 09:11:10 PM
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.

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
Bob
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
778  Camaro Research Group Discussion / Originality / Re: Did console gauge cars also have a low oil pressure switch? on: May 02, 2012, 08:37:17 PM
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

779  Camaro Research Group Discussion / Originality / Re: Did console gauge cars also have a low oil pressure switch? on: May 02, 2012, 08:01:43 PM
 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,
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.
