Great stuff. I have pictures someplace of the 00 car back when it was in 934 configuration and again when it was converted. He was harder on equipment than any Driver I remember and inevitably he would blow up something. But he was fast when things didn't break.

Are there any known examples of fully fiberglass whale tails delivered from the Porsche factory between 1975-1977?

From what I can tell reading this thread, all of the original versions were steel framed, though people occasionally mention possible, but not verified, fiberglass examples without a metal frame.

911.512.010.07 - single grill, metal frame (1974 Carrera RS 3.0 and 1975 Carrera 2.7)
930.512.010.00 - small secondary grill, metal frame (1975-77 930, non-AC)
930.512.010.01 - large secondary grill, metal frame (1975-77 930, AC)

Took some photos today of the Interscope 934 tail.

First photo I noticed how much firmer the rubber piece is than a street car

Also in the same area as the part number the number "166" is stamped

These are the factory mounting brackets for the trans cooler

I am assuming the holes in the rubber are for the extension they added to the tail for additional down force?

Nice piece of history worthy of hanging on a wall someplace.

Looks like pretty much standard early turbo with a/c tail with the exception of the oil cooler mounts.

That is exactly what the holes were used for.

No hanging on the wall for this original factory Porsche race piece. It is going back on to a factory 1976 934 that is going back into its Le Mans livery

"Looks like pretty much standard early turbo with a/c tail with the exception of the oil cooler mounts"

Looks like but it is not... the rubber portion of the wing is not pliable at all like the street wings for obvious reasons and as you said the factory mounting brackets for the trans cooler.
I could not find any part number or markings on the rubber.

Interesting. This factory tail rubber is about the same consistency as the rest. http://forums.pelicanparts.com/uploa...1413989861.jpg

Why wouldn't it be ?

You mentioned that yours isn't pliable and both these are race parts so I'm surprised that the one I pictured isn't more solid as well. Almost twice the size so the flex at speed must have pretty much flattened it.

What is yours for an RSR ? If so maybe the difference in time between development of a 3 liter RSR in late 1973 and a 934 in 1976 could have something to do with that.

However if memory serves me my friend JB who owns the real 1974 Jagermeister RSR pictured here with my 935 ... his wing has the same rubber as the 934 wing.

A lot of times is isn't picked up unless the two are side by side but the tail I pictured is about twice the size and I THINK it was referred to as the Group 4 tail?

Is this early 930 whale tail genuine?
 

Need some help in working out if this is a genuine item or aftermarket?
I only have these pictures to go by.

I vote yes, original, .... based on the light bar still remaining (tack welded to steel center support (aftermarkets do not have that feature), the cutouts in the underside to clear the bypass valve, and lack of evidence of any backyard tampering. You are still missing a couple of OEM pieces though, - i.e. plastic drip tray)
Nice find?

I say no. That light mount is riveted to the arm but also, look at the detail around the latch. Different contour than the metal ones are.
Also, the frame around the light bar appears to be fiberglass.

Looks real to me too.. as the frame around the light bar looks like it may have had fiberglass built up around/over it in the lower area moving down toward the latch (to strengthen it maybe?) The light bar appears to be metal, and some of the contours around the latch appear very close but again, maybe some built-up glass in that area?

Also, in one of the pics it looks like the underside surface has been sanded and there is metal exposed, and on the other side there looks to be some delamination starting.

Again, very hard to tell as the photos aren't detailed enough

Looking closer, large second grill tails didn't have the crossbar fully extended because the air duct went through there. It's a fake

Crossbar & latch area
 

I agree, the crossbar doesn't look right around the latch area. But it looks like I may have had a repair and fibreglass built up around it and then undercoated.
It also looks like the crossbar may be in two pieces as it seem to be coming apart in the middle.

Just put a magnet to the frame.

Gents, I've just acquired a small vent tail with part number 911.512.010.07

I'm looking for confirmation on the heat shield part number as this is missing - from a separate thread, I noted the following part numbers for the heat shield - I'm assuming the 3rd one listed?

Non 2nd grill , Non A/C optioned - 911.512.165.00
Non 2nd grill , A/C optioned - 911.512.165.01
2nd grill - 930.512.165.00

Can anyone confirm pls?http://forums.pelicanparts.com/uploa...1420330404.jpg
