1  Camaro Research Group Discussion / Originality / Re: 67 68 Camaro manual drum brakes on: March 26, 2015, 02:37:14 PM
I just installed a new master with a rear check and after bleed down good the rear brakes would drag bad and hardly release. Thought it to do with RPV so pulled it and they now release fine. The aftermarket I removed didn't have one either.
Any thoughts or ideas?

Must have been a bad RPV. Without one in the rear port on a disc/drum system, you'll probably have longer pedal travel and an obvious case of "front brakes first" (nose-dive).

<< The timing mark is off line counter clockwise from the keyway.  Just not as far off line as the 69.  For what I can grab it for I'm gonna take it anyway. >>

That inertia weight has slipped a little bit - the pre-'69 timing index line was originally aligned perfectly (within 1/4 of a degree) with the keyway and bolt hole; see note below from the upper left of the damper drawing.  Smiley

Soooo......  The correct intake # for a 1967 SS 350 engine would be 3905393 with a J266 date ?


Thanks in advance!!

If it's a Tonawanda engine, yes - that's a Tonawanda-cast intake.

I kinda like the fake DZ engine, the fake cowl tag, and the "Hoodstooth" interior.  Grin
5  Camaro Research Group Discussion / Originality / Re: Coil spring shim used to even out height ?? on: March 16, 2015, 07:03:13 PM
Anyone know for sure if shims for coil springs where used by GM engineers (typically one side) to even out a car that was leaning to one side ??  I heard shims were used but have not been able to confirm this.  I would think the shim would change the spring characteristics.

No, not ever. Dealers may have used them in the field to rresolve complaints, but they weren't released or specified GM parts.
6  Camaro Research Group Discussion / General Discussion / Re: 1967-1969 Chevrolet Camaro SS Campbell Ad Agency Proposal Mockups for Ads - INFO on: March 11, 2015, 06:30:40 PM
Those are typical paste-ups and draft storyboards that ad agency copywriters and creative types gin up and develop every day, in hopes that the client likes them and they ultimately bloom into a production ad or campaign (or, conversely, they hit the wastebasket and never go anywhere). My stepfather was a senior executive on the Pontiac account at McManus, John & Adams in the late 50's - early 60's, and he brought that kind of stuff home all the time from his creative staff to review.
7  Camaro Research Group Discussion / Originality / Re: TRICO Wiper Blade Design Changeover in 1969 on: March 09, 2015, 12:00:58 PM
The exact same blades (not arms) were also used on '66-'67 Corvettes.
Agree John but I think those used in 66/67 did not have "made in USA" stamped in.

On Corvettes, the "Made In USA" stamp (on one end of the peaked holder) started in January, 1967, and was phased in on BOTH ends by the end of the model year.

John, for greater clarity, do the wiper blades on your Z/28 have the "MADE IN USA" stamp on both ends of each blade?

Yes, they do.

Thanx for that info Johnman..
  SO let me ask ya this, any records available from this over seas distribution place still exist? If so, where would they be? What could I possibly do to find the original owner?.. Danny

Nope. Those Overseas records (and that GM Division) have been gone for decades.

My original 02D '69 Norwood Z has the "peaked" wiper blades. The exact same blades (not arms) were also used on '66-'67 Corvettes.
11  Camaro Research Group Discussion / General Discussion / Re: What starting letter should my Plates have? on: March 07, 2015, 12:16:51 PM

 I did get the NCRS info and if you recall it says GM Overseas Division, Dealer Code 1 Zone 21, possibly the Netherlands. That's why I wonder if this car was registered in the US when new. Or if a serviceman may have had it shipped.

That GM Overseas code was normally used when a serviceman stationed overseas ordered a new car through the PX system to be delivered by a stateside dealer when he got back to the U.S. - although the car never left the country, the order procedure from the PX's was handled by the GMODC (GM Overseas Distribution Corporation), as it was placed overseas.

I found it interesting that the opening shot in the video is the Van Nuys Paint Shop, not the Norwood Paint Shop.  Grin

Top one is aftermarket or Service replacement.
14  Camaro Research Group Discussion / General Discussion / Re: 1967 L78 MQ versus MR Production on: February 27, 2015, 12:41:45 PM
  It's my understanding that anything not detailed in the AIM, such as exhaust manifolds check valves and air tubes, would have been installed at the engine plant so you'll need input from someone familiar with BBCs.   

The air tubes, hoses, and check valves and pump mounting brackets were all installed at the car assembly plants; the engine was "bare-naked" when it left the engine plant. It had the correct K-19 exhaust manifolds, distributor, and RH valve cover, but that's it.

Thanks, guys! I'm 74 today, and it was 14 below zero when I got up this morning, so there won't be any burnouts today!  Grin
