That would be great, Bruce. Thank you.

Bruce, do you happen to have any photos of your rear sway bar set-up? If so, you could post them here? I'd love to see them and I bet others would as well.

Frank tells me the bar is identical to a front '67-'69 Camaro sway bar (except for the diameter). Many
thanks go out to Frank for sharing his photos and knowledge of this very rare piece of Camaro race
history. Frank has got one of the premier collections of Camaro performance and racing items and
hopefully we'll see more of it in the future.

I don't know why, how or where this stuff survived over the last several decades but it is sure great
to see that it has.

This is a good one which looks in-depth at many of the performance pieces such as cross rams, four-wheel disc brakes, etc
which were used on the Camaro in the Trans-Am series back in the 1960's and early '70s. It is not a history of the Trans-Am
series as a whole. It is a technical book focusing on various performance pieces. Very good read if that is your interest.

You're welcome, Chad.  I didn't realize you hadn't seen one of those before.

There is more information on this set-up in Wayne Guinn's Camaro: Untold Secrets book, for those who want to learn more.

2961  Model Specific Discussions / Trans-Am Camaros / Re: 69 Penske vinyl roof on: May 12, 2011, 09:44:24 PM
At the time there was a lot of speculation as to why the vinyl tops were on the Penske cars. People suspected lots of different reasons. I think one of the stranger hypotheses I've heard was that the vinyl top covered up tiny holes which released air pressure from inside the car. I don't think I have heard anything about a lowered roof but bondo and paint can cover up welds as good as any vinyl top can. I believe Mark Donohue was the one who stated that the vinyl tops were to cover up wavy roofs because the bodies of the two team cars had spent a little too much time in the acid tank. Yes, a normal unibody structure would suffer a lot from too much acid dipping and the roof does strengthen the structure of the body. However, don't forget that these cars had complete roll cages which attached to various parts of the chassis such as the front subframe, the rocker panels, the rear frame at the suspension pickup points, the side panels just aft of the door openings and it was also welded to the inner roof structure in a number of different spots. This is what became the birdcage type of frame for the car which was much stiffer than any unibody car, especially one without a B pillar behind the door, could be on its own.

Eventually, during the 1969 season the protesting of the vinyl tops got to be so much that Penske did have to have them removed and my understand is that the wavy roofs were cut off the cars and new roofs were rewelded in place, sans vinyl. It is a good thing, since Penske's cars finally started winning races with the vinyl tops off the cars and they went on to win the Trans-Am championship that year, making it two in a row.

Below are several photos of an NOS rear sway bar set-up for the '67 Trans-Am Camaro The example
in the photos is owned by Frank DiHartce and the photos are courtesy of Frank as well. This is an
extremely hard to find racing part, not intended for any street car. It is estimated that possibly as few
as 10 of these complete set-ups were made. I am personally aware of three NOS complete sets still
out there. I've never seen one, or leftover pieces of one, on any of the West Coast Historic T/A cars.
Has anybody else seen this set-up on a car?

Here's the Wedge version. Note the M/T marking on the housing also. I know Mickey Thompson had some involvement
with these but over the years I have forgotten if it was just a promotional deal between Wedge and M/T, or if Wedge
purchased the scattershild business from M/T. There are some Wedge scattershields for Fords that say COBRA on them.
Wedge was the brand that Shelby used but that may have changed by the later end of the '60s.

Did they try to section the rad supports to lower the front end profile? That would be trick...

Yes, that sort of thing (and other stuff too) definitely occured. I remember a conversation I had with Dan Lipetz, the current owner of the '70 Parnelli Jones Boss 302. He told me you can't take a stock '70 Mustang fender and hang it on the front of a (Bud Moore built) Mustang like his. It won't come close to fitting. He said you might as well be trying to hang a Camaro fender on it. His point was the fender was sectioned and modified to decrease the frontal area of the car and lower the nose. These sorts of changes occured less as you moved down the food chain from well-funded to low-funded teams.

The Washburn Chevrolet sponsored '67 Z-28 was from Santa Barbara, CA and was a very competitive "privateer" entry.
Here it is shown winning an A/Sedan race at Willow Springs. Tony Settember was the driver and Bob Joehnck was the
team manager and engine builder. This blue Z-28 is rumored to still be around as it was sold to a collector who later
ended up in jail. Anybody know of it's whereabouts?

Here is a photo of the original '68 Penske Camaro's engine compartment. This is the one that started the '68 racing season at Daytona.
This photo was taken before Daytona. It shows a Camaro-style radiator rather than the Corvette aluminum one seen later that year. The
Bill Thomas headers are yellow like Penske's crew had painted them in '67. There are many other details to see but the big one is the
magnesium factory cross ram. I know the owner of a magnesium GM cross ram, most likely the only one made and the one that is seen
in this photo.

Really cool, Chad. Thanks for posting!

Anybody else have more of this for Firebirds?

Thanks, Bruce. Hey Chad, would it be possible for you to post the Firebird SCCA paperwork you have? I've never seen it before and would love to see more.

Here's a photo of Craig Fisher's 302 engine in his '67 Gorries "Black Panther" Z-28. This was taken during tech inspection for Sebring, late March 1967.
At Daytona in early February, the car had the power brake booster and the cowl plenum duct to the firewall but as you can see they have already been
removed and modified for Sebring.
