Silly question, but what would the good terminology be for a search?

A vast majority are repros so you will want to verify what you have to estimate value. The originals have a 930 part number on the side metal base and a functional small secondary grill. Porsche made this tail only in 1975 and 1976 for non-optioned A/C RoW 930s. The '75 tails are different as they don't have the indendation by the wiper motor, a good estimate for production #'s for 1975 model year is around 137 made (one half the 274 total production). For 1976, again about 327 (one half the 654 total production) so a total of ~464 factory tails made with the small secondary grill. There are probably 3-4 times that number out there that are repros and I have a repro hanging in my garage. For reference here's an original on my '75 Turbo - The original OEM tail thread collective documentation

"early turbo tail" seems to work for me...

Was there a tail without the grille used on any of the early production turbos? I don't recall seeing one... maybe I've never seen an early turbo that didn't have A/C. What's different about your tail, than a tail on an A/C-equipped 930?

Where exactly is that part number on your tail? If I end up scraping paint to find it I want to be 100% sure where I'm looking first.

I certainly have the functional vent with the shroud to feed the fan:

Except they also used them on the Carrera 2.7 and 3.0 cars so the numbers made are really hard to say.

Two spots I've seen for part number. In the middle of the small brace near the striker and on the metal frame at the side. I have an early '75 (no half moon cut out) and the part number is on the side. See circle in photo below. There are a few on eBay with crazy 'asking' prices. -J

Thanks for the heads up, and simply wow on the Ebay asking prices. $3500 is some serious cash.

Yes, "Ebay asking prices."

I find that most that need them have them. So the question is what will those that want them actually pay?

I'm thinking close to $2k is a pretty reasonable price these days.

I've been working on the whaletail section for my mid-1970s Porsche book and there is quite a bit of confusing information out there (fiberglass weaves, part number stampings, frame steel vs fiberglass, heat shield variations, paint variations, detecting reproductions, etc). Attached are the parts lists for the whale tail from January 1975 Spare Parts Catalog. This should be very enlightening to this discussion on the 1975 930 tails. Thanks to Joe Hartman for providing these period parts list pages.

Reminder: PET parts catalogs (especially the modern PDFs) show REPLACEMENT parts and not always what was originally fitted. Porsche removed parts all the time, and combined parts, to simplify their production as well as inventory management in the decades that followed. Anyone relying on modern PET parts catalog for a restoration can inadvertently end up with wrong parts for their car. Original period Parts Catalog, such as this eBay version give much better insight.

[javadog]

You're quite right about the parts catalogs. The original paper versions are the only reference worth using. Still, I wonder if they are infallible. Looking at that portion shown above, the entry for the US '74 Carrera puzzles me.

Any chance you'll cover the Carrera 3.0 in your book?

JR

[rsnodgrass]

The paper ones have issues too as they were revised twice a year. The best is to get one closest to the build date for your car. However, anything from the 1970s is WAY better than the ones we get now. Researching various parts from 1974, even the 1975 spare parts catalog is missing things. Notably any diagram or part number for the ducktail!

Some of the details of the Carrera 3.0 (and 75-76 930s) will be highlighted where they are related to Carrera 2.7 MFI production, but we stop at 1976, therefore anything 1977 specific (like the Sport polyurethane whale tail) won't be covered.

[GWhite]

The ducktail is there Ryan it's part number 911 512 905 00. referenced to the diagram as (2) meaning a part only similar to the illustration. (well they are all spoilers)

It correctly lists it as an option for the Euro Carrera (although strictly speaking it should say only 1974 my) but doesn't list it for the US Carrera where it was standard for 1974.

It correctly though lists the whaletail as standard for the US Carrera (again strictly this should be 1975 my only) with the flat lid being an option. (opposite way around to the rest of the world)

Aha, now that you pointed that out I see 911 512 905 00 in the line above where I wasn't expecting to see the part. I also had never noticed "And-Nr./Mod-Nr." with 1 and 2...see below for a legend of the indicators (from the 1-79 version).

It also mentions the "M" indicator in the column is "Additional equipment/reduced equipment/optional equip" so items can be deleted (reduced).

If you all are interested let me know and I will post detailed photos of a factory 1976 934 rear wing. Unbroken chain of ownership since the factory so I know for a fact it is all original. Fiberglass on a metal frame with a rubber lip. Ran a couple of races before being switched out for the larger 934/5 wing so in great shape.

930 512 010 01

[group911@aol.co]

I'd love to see some detailed pics. I had one also and would like to compare.

Very cool...it would be nice to see detailed photos.

That is the correct part number for the 934 tails as they ran the stock 930 tail with larger secondary grill but of course did not use A/C parts for the race cars (transmission oiler cooler instead of A/C condenser in the secondary grill). In FIA Nr. 645, Porsche homologated the production 930 with both tails (93051201000 - no A/C and 93051201001-A/C) in order to meet the 400 number count prior to the start of the 1976 racing season.

[VZ935]

I will take some detailed photos this week.
And correct the 934 ran parts off the street cars. They had door panels with the factory pulls, power windows, cigarette lighters just in case you wanted to fire up on that long Mulsanne Straight.

Here is a wing from the same team (guess who) but this is an original Kremer piece.
