Here is my T/G Firebird rear axle, it is partly restored, i was mocking up the Watts linkage when this was taken.

Here is one of the hybrid rear axle. The centre section is from the Pontiac big cars, like the 455 powered station wagons etc. As Jon pointed out above, they have a 12 bolt ring gear. The axle tubes are from the F body so they are the right width, and have the appropriate mounting points.

The outer wheel bearings have an inner race so don't run directly on the axle shaft. 



This has the extra 'box' added to the rear cover to increase oil capacity. The two tubes are copper and pass fresh air through the middle of the oil.

The second pic is the axle without the extra box added. It also shows the various linkages and bars.


I will try and find a pic of my axle as it is now. These are from period articles.

One more from a different angle

Here is a pic of one of the T/G racing rear caliper mounts. It looks to have been milled as opposed to cast. You can see the bearing and collar, the caliper mount bolts to the flange on the end of the axle tube, pressing the bearing into it's seat and retaining the axle, No C clip like the Chev rear axles.

That is a neat article Jon, i have seen some of the pics used in another very similar article somewhere.
I notice a few points worth mentioning. T/G were sent engineering mules as the basis for the race cars. these were cars that were used for testing some aspect and never destined to be road registered. If not used for race cars they would have been scrapped.

In one of the pics above of the special taller front spindle you will notice that the top of the Corvette brake caliper mount has to be 'clearanced' to make room for the extra length (height) of the spindle. The parts are pretty much identical to the ones used on the race Camaros, but they were assigned part numbers on the race Firebirds.

So many neat details in the pics,

Thanks for posting those Jon.
Bruce.

Further up in the pic of the 303 cubic inch Pontiac, you can also see the locating stub for the radiator support on the front of the frame rails just in front of the roll cage extensions. This was part of the quick removal of the entire front end sheetmetal to make servicing and engine changes quicker.

I see they had their tall (but not as tall at Penske) fueling tower built before the start of the season.

Thanks for the added background Robert.

Dave's Can Am McLaren is back out on the track in the old color scheme. It is now owned and run by a Kiwi who is living in Washington State.
Dave moved his business from Barrie a few years ago. He re opened elsewhere with a slightly different focus. I exchanged some emails with him a while back and he was very gracious with his help and knowledge about the Titus engines.

Those photo passes are great Jon, What neat souvenirs. 

Just a note on the above Jerry Titus engine shown above. It was built by Dave Billes, at his Performance Engineering Ltd business in Canada.

That is always the issue with models that are absolutely correct, and the same is true for full size restorations. We have all seen properly restored race cars that have their quirks and stranged facets, but it is those details that make them correct. i'd rather have them "right" and perhaps questions, than the way people expect. Juat as long as the facts and pics can back up the restoration.

More great work Mike. Keep it up.

Hi Jon,

I had a look at the Freidman book and the Bridgehampton section has Jerry with the big old 13 on the door, but I'm open to correction,

Nice progress Mike, The front is looking very close to the real thing, The indicator overlays did look crude on the real car, but they did the trick at minimal cost.

That looks to be the pics behind the reports, Both cars are # 37 but it certainly looks like Jerry in the car. I wonder if they kept trying to run the spoilers until the SCCA relented. I will have to trawl through all the on track Firebird shots and see which had this type of spoiler.
I am also weary of relying on the book photo captions.   Jerry was using his #13 at Bridghampton

Re the Titus Firebirds running without spoilers, I believe that they turned up with aftermarket (ie non factory) spoilers, the front had some funnel shaped ducts, this was questioned by the SCCA, and they had to remove them before the race start.

Stunning photos Jon, the background knowledge of the cars, drivers and circumstances makes it very enjoyable.
Boy, they drove those cars hard and there is a LOT of panel damage. It's surprising any survived,

You time and effort scanning and posting all those pics is very much appreciated.

Fantastic work Mike,  I love seeing the detail that you include and the length you go to.
Truly insirational. I can't wait to see it finished.

That is very sad news indeed. Chic Vandagriff and his family were heavily involved with so many very notable and sucessful race endevours.
My condolences to his family.

Bruce.
