Gt40 - GTD Chassis Number

Hi all,
I've been reading the forum for a few days and I find it very interesting.
I'm about to buy my first GT40 and it's a 1989 gtd.
I would like to decipher the frame to see the originality if you can help me.
Thanks in advance to everyone.

Hello joojoohe,

Wellcome to Gt40s.com.

If available you should post more detailed pictures of the car - then members can comment your question....

 
This thread may be useful

Post pics of front and rear chassis. GTDs are easily recognised.
Cheers
Mike
When find the front and rear chassis number?
I only have this scans for the moment

HI

Not a chassis number matching any record I have, sorry. GTD chassis numbers in 1989 were five digit and ran between 13989 and 19889. GTD stamped their chassis numbers directly into the chassis on the cross member where the pedal box mounts, the forward cross member not the one nearer your feet.. No chassis plate per se. Hope this helps.

As Malcolm says the chassis number is stamped into the front crossmember. It may have been covered by panelling. The number is also sometimes stamped into the crossbar at the very back of the chassis.

Your pics show the engine and interior. We would need pics of the front and rear CHASSIS/ suspension to see if it is GTD.
Cheers

Info from a previous post

GTD chassis numbers

In 1989 the chassis numbers began at 13989 and it was a good year for production as they got up to 19889. If you look at 044 then the 44th chassis was built in 1986 which makes the chassis number 4486. Then again GTD40 as a prefix was never used until 1991 and the first was GTD4026991 ie after 268 chassis made. The 44th chassis was put into stock and the buyer is unknown as is whether it was a kit or a completed car.

Up till 1990 no GTD chassis number had GTD in it. Thereafter the chassis number had GTD40 in front of the chassis number. After 1994 the Poole area dialling code of 01202 and some zeros were added to pack it out to meet legal requirements. So my chassis number being the 254th car made in 1990 is 25490, then you had say GTD4027091 and then GTD40012020037099. After that then you get into licensed territory with it going GTD4RW or RS at the beginning instead of GTD400, dependent on who made what and when. But there are not many of those chassis numbers!

e.g.If VIN on the frame is GTD40 01202 00370 99
The code is quite simple.
The first 2 characters - '40' are obvious.
The next 5 - '01202' - is the area code for Poole, where the GTD factory was.
The last 2 - '99' is the year of manufacture.
The remaining characters - '00370' is the serial number.

Nothing pre 1985 although I suspect Ray had started GTD work before. 1985 had 10 chassis listed. 1986 had nearly 40 chassis numbers listed. And they went on from there

Last GTD. Believe it was GTD40012020037099 and this one went to Brian McCarthy.

Wow, one certainly couldn’t ask for a more detailed response than that. This forum is full of so much knowledge it blows me away some days.
Nice job Mike.

Regards Brian
 
Thank you all so much for the quick and thorough responses.
You guys are truly awesome and have convinced me to let this car go.
Cheers

It was not completely uncommon for customers to put their own chassis numbers onto a car. Look for the chassis stamped one. Thats the one that matters. Other items look GTD but need more chassis pictures to be certain.

Yes, I imagined it but I'm not convinced by the smell since he doesn't show me the stamped chassis number and so I'll move on.
Thanks

P.S.:
Hope to find a nice car near me in Italy... i really hope because i'm really interested on it.
If somebody knows some genuine early gtd40 in Italy please contact me.

The fact that the chassis number can not be found is not a big issue and not a deal breaker.. The chassis can be easily identified from pics. These cars are worth the sum of their parts. It is important to know what specification parts are fitted to the car.
Two points
There should be a chassis number on the paperwork.
If the car chassis is a GTD it will be obvious to forum members by looking at pics of the front and rear chassis/suspension.
The engine looks to be a Ford small block. The cooling system header tank looks to be of an original pattern. It has a crossover exhaust system. I can't see what gearbox it has from the pics. Someone has put some effort and money into the car. The uprights and brakes are unknown as there are no pics. The wheels may be 15" . The tyres look like BF Goodrich not Avon cr6zz.
If the car has paperwork to enable it to be registered for the road in your country it is worth further investigation. I would suggest that you investigate the car further to find out what all the parts are and their general condition.
Cheers

Hi Mike, thanks for reply.
The engine is a Ford Racing 5.0 with 500HP (he told me), the gearbox is from a porsche and inverted, very parts are like original and the strumental are Smiths, he did very works on it over the years for look the car to the original GT40 specification.
Also when i told him that the chassis number must be in front he told me that he checked it and it isn't and told me maybee he did some works on the front years ago maybee the chassis number is missed or deleted, anyway the car is registered for the road and is ASI (historic car register in Italy ) from 2008 and has the plate to circulate.
I send some photos he send to me now;

There was a member on here a lot of years back with the surname Batt…….I wonder if this is his old car and he added his name in the chassis number?

It may be possible that the 302 has 500hp but I doubt it and would want to see a dyno or rolling road printout before I believe any hp claims. The engine may have good aluminium heads but the pics don't show this. There appears to be a 4 barrel carb which may be a Holley or Edelbrock.. From the size of the carb it does not appear to be a Holley double pumper. Ask the seller if they have a build sheet for the engine.
The inverted Porsche gearbox is most likely a G50 which is a good strong box.
As there are no suspension pics the uprights and brakes are unknown. The pics of the front and rear chassis are not available to see if it is GTD in origin.
The exhaust manifold usually fitted to GTD40s was a non crossover type and this car has a crossover manifold. The collectors are a bit basic. The seats originally fitted to GTD40s were leather seats with metal eyelets and were sat on metal frames. The seats in this car are original type fabric seats with eyelets. These items may have been fitted to make it more original looking.
The body is a replica style shape as it has the ridges at the top rear of the doors - original 40 bodies do not have this ridge.
The general condition looks good. It has the double front nostril panel. The rear window is plastic rather than glass as can be seen with attachment screws.
Cheers
Mike
