Title: 1967 Camaro radius rod research
Post by: KurtS on January 23, 2010, 03:04:17 PM
I just updated the radius rod article, http://www.camaros.org/radiusrod.shtml, with new pics (thanks Ron!) and new information. But we really don't have a lot of clarity in the data, especially for the first cars that used radius rods.
We are looking for more information from any SS, Z, or L30/M20 that was made Dec 66 or later. Especially SS350 cars made in December or January and L30/M20 cars made in December thru March.

You can email the information below to either me or Daniel (CamaroDan@juno.com) or to post it on this thread.
The information that we're looking for is:
1) Build date
2) Model (SS350, L35, L78, Z28, or L30/M20)
3) Does your car have a radius rod? If so, round or rectangular?
4) If not, does it have either the body bracket or the axle bracket?
5) VIN (Feel free to email if you don't want to post it. We need to the VIN to be able to sort and reference the data. It will not be published or released in any form.)

Helpful extra credit (esp for the early SS350 and L30/M20 cars). :)
6) Axle date (e.g. QJ0421G1). See http://www.camaros.org/drivetrain.shtml#axle for the location.
7) Do you have any documentation for the car?

Thanks for the help!!

The report still could use a better pic of the round bar installed in a car (same angle as the rectangular bar would be great) and some pics of the axle brackets (without a rod installed).
If anyone has a dealer-added bracket/rod, that might be a good pic too. Not sure if pics would show the differences though.
Thanks!

Buddy,
Do you still have the maroon BB?

Philip,
They didn't install a rod on 10 bolt axles and the L30/M20 didn't get a 12 bolt until a couple of months after your car. Thanks!

I am trying to verify if this is the original differential.  I snapped some quick pictures and tried to get some numbers

Build Date: 01C
SS350
No radius rod since I have had it
I will PM you my VIN
I have the POP only.  Havent found a build sheet (have not looked too hard yet).

Build date- 2B 3L/4P L142305 has the bracket, no rod, no axle bracket. But my mystery is a 10 bolt rear! Could this original? The date lines up perfectly for the car

I just updated the radius rod article with pictures that Ronald and David and David and Jared have sent me over the past few years. Some really nice shots of the axle brackets and now the floor bracket.
Photo credits appear when you hover your mouse over the picture - I think I got them all right. :)

Kurt, you have the info on my car. I bought it from the original owner in 1984. It is an L48 m-20, 3.73 car. The original owner states that the car was recalled to install the radius rod. It is square, and they didn't use the brkt under the rear seat. There are two bolts and lock washers holding the front radius rod brkt.
Title: Re: 1967 Camaro radius rod research
Post by: Mike S on March 27, 2014, 09:50:29 PM
 There should be 3 bolts holding the front bracket. Two against the floor and one to the side rail.

Does anyone know why or when the change of the axle bracket came to play on the Second Design - Rectangular Radius Rod. I've seen two versions, one have a press mark and the other having a hole drilled just above the side dimples? I'm surmising a June of 67 change.

 I assume the square was needed to handle the larger engine torque and also the additional snubber bracket added as a means to limit the rears travel due to spring wind. As for a transition period I don't know when. We can only get a rough approximate from the dates within the assembly manual but that's not exact when it hit the production floor.
  The two Camaros I have with original rears are one 'BJ' rear (3:07) stamp dated 0404 for a LOS 4B (April 13th per UOIT) dated trim tag and that has the round bar with no holes provisioned for an additional bracket. That car has the L35 w/TH400. The other rear is a 'QK' (3:31) stamp dated 0331 for a NOR 5B dated trim tag and that has the square bar with the additional bracket for the snubber. That car has the L35 w/4 speed.

Mike,
Thats not what I'm asking. I'm referencing cosmetic looks on the bracket welded on the axle tube for the square bar.  I've seen some with press marks and another with a hole on the backside of the bracket. It can be viewed on this link       http://www.camaros.org/radiusrod.shtml
Title: Re: 1967 Camaro radius rod research
Post by: luv2sixty9 on May 21, 2014, 07:05:55 PM
On the lower pictures; first picture you can see the circular press marks just below the side notches. And on the last picture you can see the factory hole just above the side notches. Thats what I'm asking about.
Title: Re: 1967 Camaro radius rod research
Post by: Mike S on May 21, 2014, 07:11:39 PM
 I see the hole now....its dark in the picture where you can't notice it unless you know it's there.
 I'll check my car when I get home to see if it has that lone hole in the back.

Mike
Title: Re: 1967 Camaro radius rod research
Post by: Mike S on May 21, 2014, 08:50:43 PM
 Here is a picture of the 'BJ' rear dated 0404 on the '67 04B LOS L35 w/TH400 transmission.
This has the round radius rod and you can see this has the hole in the rear.
I looked at the 'QK' rear dated 0331 and this has the square rod w/stop bracket. There is no hole on that axle tube bracket.
It would be interesting what the hole was for. Maybe to hold and/or strategically place the bracket on the tube prior to welding?
Could be an interesting poll to add to the CRG article.

Maybe something like:
Date   Code     Radius Rod        Rear Hole
                    Round/Square         Y/N

Jon,

  First, thanks for adding to the research.
I think I see a pattern already between the bracket with the hole vs. the one without it.
From what I see in the CRQ report pictures and on my 2 cars is the one with the hole also has a stepped 'notch' in the very rear of the bracket on the bottom.
The bracket without the hole is flat along that rear edge. Can you confirm if yours are that way too? That would make it sound like there were possibly two suppliers of that part or a change in the way it was stamped and no other meaning for the existence of that hole.

Thank you,
Mike

no radius rod

Thanks Kurt for the info on my car.  I knew it was owned at some time in the past in PA.  I was told that was the second owner.  The third owner restored it in MO, and I bought it from him.  So as far as I know I am the fourth owner.  I had tried to find info about the original owner but to no avail.  The NCRS shipping report only shows it going to the Cleveland Zone Office; no original delivery dealer is listed.
