1972 911 S Coupé, please help me ID odd brackets (rallye, racing?)

[jsoderbe]

Hi,

I'm currently dismantling my rather sad 1972 911 S Coupé, before I'm sending it to the sheet metal guy. During the excavation I have found some strange brackets and stuff, that I was hoping someone can help me ID.


Strange bracket near the torsion tube area I haven't seen before:



Mounts for a roll cage on the fire wall?



Mounts for a roll cage under the seat belt mount?



Reinforcment for the rear sway bar mount:



Strange power outlet, mounted under the dash, above the passenger right knee. This is connected to the fuse box, and it looks like a very tidy job (or was a tidy job before I started tearing it apart):



As you might understand maybe I'm reading too much into this, since the dream would be to find a rallye/racing history for the car.

The car itself is an early 911 S, nr 211, built in November 1971. It was exported to Sweden in 1986. By then it had a G model Turbo wide body and was painted red, equipped with a 2,7 instead of the original 2,4 S.

From the history of the car I am pretty sure all the mods on the pictures were made in Germany, early in the life of the car. The reason, even though I'm not entirely sure, is that it looks like the mods was made when the car still retained it's original green metallic color.

Any ideas or insights would be very appreciated!


Thanks,

Johan

Just guesses:

Maybe a rally car and some of the under the car might be for skid plates?

Not sure about parcel shelf holes. Would not expect a roll bar there but maybe some type of rack mount for a spare tire or tools.

Thanks for sharing. Way cool!

The top pic is an "I dunno"...but I can tell you that my former car, an original '72 S, had the same thing. No idea what it's for.

The rear torsion bar mount holes are correct. That looks like an after market "skid plate" of some kind below those holes. Again, not factory...

All the other stuff looks to me to be done after the car left the factory...

Hi,

thanks for the support guys. I've done some research, and it looks more like rallye equipment than racing.

The reinforcment around the sway bar mount is to avoid getting stones and things to rip off the sway bar. That can be used both for rallye and racing.

The electrical connector could be power outlets for co-driver light, trip calculator and possibly intercom.

The welded in nuts are roll bar mounts, but strangely enough I don't have any mounts in front of the driver.

The reason I'm leaning towards rallye is that the floor is really worn, and have dents of different sizes all over.

It doesn't look like it's a factory rallye car, since I gues they have all different kinds of modifications. So I'm guessing the modifications were done mid-seventies to early eighties.

Does anyone have an idea of how to find out German rallye history from 1975 to 1985?



Thanks,

Johan

On the roll bars of that time the rear bars bolted to the rear seat belt point. The were just a hoope with two rear leggs. Usally did not even have a cross bar in most.

[jsoderbe]

Thanks, that is surely the case with the roll bar.

It's getting sandblasted as we speak, so maybe I can take some better photos later in the week.

Someone told me the torsion bar tube was reinforced? I can't see that, but maybe someone here can?


Thanks,

I screwed up...typed torsion, but I really meant rear sway bar...sorry.

Unreinforced


The below is a real ST. The reinforcements vary with who does the work.


It is impractical, but not impossible, to reinforce the driver side anti-sway bar mount on 1971 911s along with a few other years. This is due to the Bosch MFI electric fuel pump being mounted on the upper surface of the anti-sway bar mount. Mine broke on the passenger side so I got it reinforced when I replaced it.

Hi again,

I have been doing some research, and I have found some interesting stuff. First of all, tha car is equipped with reinforcments around the torsion bar tube, looking like this:



That is not from my car, since it's still at the media blaster. It has also reinforcements around the front suspension mounts, but that could be rust repairs as well.

This is really exciting, the only downside is that it looks really hard to get any information from 1975-1985 when it might have been raced/driven in rallye.

Any thoughts or ideas would be very appreciated!

The VIN# is 9112300211, and the car was delivered Oct 1st, 1971, in Green Metallic with Leatherette Black/Pepita.



Thanks,

Johan

That is an anti-sway bar reinforcement. The torsion tube reinforcement are some flat pieces of metal connecting the torison tube to the chassis/floorpan sheetmetal ahead of it. What kind of front suspension reinforcements are there? There are standard, small flanges that go on the front A-arm mounts, welded to the suspension pan.

There are also these front suspension reinforcements.

[jsoderbe]

Flieger, the front reinforcements looks like that, but unfortunately not as neat as yours.

I'm not sure what you mean by anti-sway bar reinforcements. They are there on my car, but there are also the reinforcements around the hole you put the torsion bar into (whatever you call it in the us....). That can't be original?

It's somewhat frustrating to not being able to find out more about the history of the car than I have so far, when it is obvious it had an interesting past!


Thanks,

JOhan

Those reinforcements are not my car. I found them on the Early 911S Registry.

The anti-sway bar mount is right under the hole for the torsion tube. Maybe that is where we are not seeing eye-to-eye. The photo you posted shows the reinforced anti-sway bar mount, but does not have a view of the part of the torsion tube that gets reinforced for a separate modification. It is in the center of the car, and helps the torsion tube transfer torsion and bending loads into the rest of the chassis. See post #7

[Flieger]

Oops, silly me!

I was looking at the obvious anti-sway bar reinforcement in your photo and got distracted, not noticing the extra sheet metal on the outside of the torsion tube hole.

Thanks for the image. That is a good reference.

[jsoderbe]

that reinforcement was news to me too! I got it from a german 911 forum....

Thanks,

Johan
