Chassis numbers

[SSP]

Hello all,

I need help with a Production/Control number stamped on the tunnel under access cover for the gearbox coupler. I need someone who has the factory list to cross reference the chassis # to the production number and vise versa. Anybody’s help would be appreciated. This for a early 911 car in the mid to late 60's

Thanks, Scott

Come on guys?! I told Scott someone on this board could help him out on this. Dosen't anyone out there have a cross reference for production numbers to chassis number? The car in question is a late 65 or 66 911 that is being restored and brought back to the road. Please do your part help get this very early 911 restored.
All the best!

Probably the only way to link a production number to a serial number is at the factory in the archives by flipping through the production books (if allowed).

I am aware that the (Reuter?) production books up to 52 are copied but I have not heard of copies floating around for other, more recent years. Those production books would be your only help I guess. The well known Kardex build sheet doesn't show a production number.

Just my $.02

not sure I understand your question but in Dr. Johnsons book, it lists chasis serial numbers for the various yrs.

Model Yr. 1965
Porsche Coupe 300 236 - 303 390 > from Jan. to Jun.


Model Yr. 1966
Porsche Coupe 303 391 - 305 100

was this what you needed?

Hmmm....so my 911 with a chassis number 302981 was considered a 65? All this time I've thought it was a 66!

66? 911

There is some confusion in reference books with the numbers for 1964, 65 and 66 due to some people using calander years for production (applicable to 1964 only as the first production cars were made for September that year) and others (incl the factory) using production or "Model" years (August thru to July).

Car 302981 was within the 1965 production year and was produced in 1965 before production of 1965 models ceased in July 1965 with car 303390. From the number it was probably prduced in about late May 1965.

In Australia that would be considered as a 1965 car. however i have read somewhere else on this board in the past that IN THE US all the early cars made in 1965 were registered as 1966 cars for some reason. I dont know about that but someone else on the board will.

None of this answers SSP's question about cross referencing the Production number of a car to the Chassis number.

However I thought in the early years (maybe up till about 1968 or so) that the chassis number and production number were one and the same. It is only into the late 60's and 1970's like my car that the production number is different to the chassis number. Is that not so?

If so the numbers that boxster03 posted should help although I have them (From Aichele's book which had full factory access to original records) as:

1964 300 001 - 300232 produced after Sept 1964 until Dec 31 1964

Model Year 1965
1965 300 233 - 303 390 Jan 1 to July 1965 911 coupe Porsche produced
1965 350 001 - 351 970 Jan 1 to July 1965 912 coupe Porsche produced
1965 450 001 - 454 470 Jan 1 to July 1965 911 coupe Karmann produced

Model Year 1966
1966 303 391 - 305 100 Aug 65 to July 66 911 coupe Porsche produced
1966 351 971 - 353 000 Aug 65 to July 66 912 coupe Porsche produced
1966 454 471 - 485 100 Aug 65 to July 66 911 coupe Karmann produced

I have a strong believe that the quote's below are incorrect.

Car 302981 was within the 1965 production year and was produced in 1965 before production of 1965 models ceased in July 1965 with car 303390. From the number it was probably prduced in about late May 1965.

Model Year 1965
1965 300 233 - 303 390 Jan 1 to July 1965 911 coupe Porsche produced

Model Year 1966
1966 303 391 - 305 100 Aug 65 to July 66 911 coupe Porsche produced

I have seen several Kardex build sheet and this conflict w/ the information.

Car 302981 was most likely from december 65. Car 303056 (75 after) left the factory at December the 12th. Car 301784 left the factory July the 20th.

It's also seems low that Porsche only produced roughly 1700 normal 911s cars in 1 year?

That is what I have heard. I have a '68 apart in my garage right now and the production number stamped under the kneepad is the same as the chassis number. However, the number stamped under the access cover for the gear shift coupler is different. It agrees for the first 5 digits and then deviates.

I'm going with Richard on this one, my understanding is that the cutoff for Calendar year 1965 production was the 303390 car. I've seen previous discussions on this subject, and also have seen it in print (must dig it up...). The reasons for the previous discussions, and why it was in print, is that they have a specific rally class in Europe and the UK which has the end of 1965 as a cutoff (or they did). So the pre 303390 cars were always more valuable as they could be rally'd in this particular class. I should also note that I owned a 65 911, and had conversations with Francis Tuthill on this subject while I was selling the car... (Francis builds rally cars in the UK).

Richard / Eric

That is why I prefaced the post with comment that "there is some confusion".
I suspect Eric is correct with the last car for 65 which would tie in with what Richard says he has seen on actual production records.
It is not however what is in the books. My rule of thumb check was to work out how many cars were produed a month or day up to 1968 (while consecutive numbers were used) for each period.
Initially in 1964 there were about 3 produced a day.That ties in with the records I have seen for the first 33 produced up till Oct 8. If you use the numbers I posted above ie 303390 at july 65 then all the others as published that implies in the first half year of 1965 about 22 cars a day, for the 66 year about 8 cars a day and for the 67 year 16 cars a day. However if 303390 was December 1965 and all other cutoffs unaltered (ie the 1966 cars as recorded were produed only between jan and july in 1966) there would be about 14 cars a day over the whole of 1965 caledar year and 12 cars a day over the first half of 1966.
To me it makes more sense but I am yet to see a set of publised records with those cutoffs.
