Watts Linkage And Other Locating Devices

Here is the rear deck area.

You're correct.  I knew it was a school!  Do you know if anyone ran a top link?

     I guess I'm not sure what that is.

Anybody have the pic of Donohue sitting in a Javelin, can't remember which year, but there's a red Koni or something in the pic behind him,  mounted just above the driveshaft tunnel.   Ken

     I think I recall seeing a photo like that at one time but I don't have the image saved or anything.

The 70 Bud Moore car #775 had a three link set up but Parnelli set faster times in the normal suspension car so it was removed. You can see what remains of the brackets and the three link that they all had. This car had a very high rear deck area in front of the rear window inside the car and the rear shocks were outboard of the frame rails too. You can also see part of the over ride traction bars where they pass through the floor.

    Thanks for posting these! Is that #775 or #776?

776

[Jon Mello]

Thanks. #775 has not been found to my understanding. Is that correct?

[1109RWHP]

Correct. Might be a chicken coop in Mexico as far as anyone knows.

Top link is a center mounted traction bar a' la a three link.  Solid or spring loaded.  Sounds like 1109's description of a Donohue photo answered my question.

Keep the pics coming guys, this is great info. Many thanks.

   I may have a photo and info in my files showing the rear suspension setup and student designed traction device on The University of Pittsburgh Camaro.

I really would like to the rear suspension on the #19 car.......not been able to closely look at the suspension on this car

I posted in the General Discussion Forum looking for information on my 1969 Camaro SS 396 / 375.  Based on the owner history / information available, it appears to have been modified when new for some form of racing.  The most interesting modification I found are stout brackets welded to the rear frame rail kick ups and what's left of the corresponding brackets that were welded to the top of the differential housing tubes, just inboard of the leaf spring 'U' bolts.  It seems that some type of 'override' traction bars or shocks (as pictured in the Chaffey College car photos) were installed. Additionally the car had a full roll cage previously installed and later removed prior to 1973.  I believe the car was set up for drag racing but I've only seen the underride type of traction bars used for 1/4 mile cars.  Any thoughts?

[Jon Mello]

It would appear that the car did have Hi-Tork or Koni horizontal shocks at one time like the Chaffey College race car, although mounted
further outboard so they were outside the rear frame rail. Maybe this car saw some autocross/gymkhana/slalom activity, but it is unusual
to see this stuff on a big block car. I agree that you would expect to see the much more common traction bars mounted under the rear
spring on a car like this. Thanks for sharing the pic.

Here are some shots from the Jerry Lagod thread showing his rear suspension, including the Watts-link, double-adjustable Konis, J56 brake calipers, rear sway bar, etc...
