Hi, here are few photos of my carrera 3 - body/interior original, all number matching. engine modified to carbs
Headlight washer nozzle - need a tall one, N/A from Porsche. Tail same as your - original from Porsche when it was imported to Japan.
Back in 1977 the ducts that go to that small squirrel cage just outside the engine filter intake were made of black plastic. They found that the things would melt due to the temperatures from the top of the engine. Clearly, that happened to your car because that thing is missing. The solution from Porsche AG was to hot wire the interior-heat squirrel cage that feeds hot air to the cockpit and have it come on all the time, not just when you pulled up on the interior heat controls (the two red-handled levers between the seats). This was all done in an effort to bring more heat into the cockpit. Simply pulling hot air from the heat exchangers fed by engine speed was simply not enough. It needed an assist from that small squirrel cage.
1977 was a very odd year for Porsche. Many things were one-year things. I suppose it was because they were making bigger plans to introduce the 911SC in 198 and they didn't want to have to do too much to get them past a model year (1977). The steering wheel kinda sucked, the thermal reactors were worthless and introduced too much heat to the valves. They simply were pushing the thermal properties of a magnesium cased engine too far. 2.7 liters was too far--3.0 for sure. When the 911SC was introduced as a 3.0 liter it automatically came out with an aluminum case--the ultimate solution!
I do recall those terrible all-rubber tails. Why they couldn't have put on the smaller whale tail from the 3.0 turbos is beyond me! They had to develop the ugliest tail that they could. Nuts!
I was so glad to dump my '77. As yours appears to be a 3.0 liter car, it's a different animal for collectibility. It was the gap filler from the lousy late 2.7s to get us to the great 3.0 SC!
Also, your interior is pre-77. So, it's been messed with a bunch.
A car I looked at but ended up not buying had one of those rubber tails. I don't get why it's so universally reviled, seemed ok to me. If I had bought that car I would have left it alone.

again this is stock '76/77 C3 engine, I never heard of any issues w/ the aux heat motor on the left or the ducting, I did need to replace the motor brushes at ~the 20yr mark. The blocks on these C3s are the same as was used on the later SC, Carrera, 964, 993, 996GT3, 997GT3. These al. crankcase halves are different from the developmental al. blocks used on the 3.0 RSR, IROC and 3.0RS in '74
steering wheel on my C3 was a nice thick 3 spoke,
no thermal reactors either on these, though the stock design sucked from a flow perspective, a nice set of ssi's solved that issue
Np air pumps either, SC did have these
for their time the C# was much faster than most anything else, certainly quicker than the similar later SC, it wasn't until the '81 SC that they reached 200hp again though in a heavier chassis
The rubber tail is almost a clone of the f/g tail, the difference is construction material, the f/g tail was bonded to a steel lid and had a p/u lip, the black was was all p/u bolted to a steel lid. The f/g tail has the base painted body color, the 1 piece is all black. The issue is weight the bolt on black p/u piece is 20# all by itself, + 9#s for the steel lid, even the heavy 930 teatry only weighs 23# w/ lid
My theory as to the genesis of the 1 piece tail was they needed to be able to add aero parts either late in the assembly process or after the car left the assembly line. The 1 piece doesn't need paint and like the front lip is a pure bolt on to stock parts.
I am expecting delivery on Tuesday morning. It will have taken a solid month to get from AZ to SC, my only complaint so far with the process. B-J uses Reliable Carriers which is set up on site to arrange transportation. When I called last week to complain about the long delay I was told they had to ship 700 more vehicles than they were expecting? Seriously? It is not their first rodeo. If I ever go again I would drive the car off site and arrange my own transport.

Slight thread hijack but what part number are the motor brushes and where did you source them? Thanks!
This was decades ago. I went to a local Electronics repair shop, They had boxes of brushes, I went through them till I found a set that worked.
I don't think that such shops are common any more
That was my concern. There was a time when I'd pop down to Radio Shack for oddball electrical stuff but not any more... there might still be a local guy rewinding motors in his garage though, I'll have to do some digging.
Car arrived with a dead battery. Put a fresh one in, was able to drive it a couple of miles to my house. Parked, turned it off, won't start again. Definitely has electrical issues. Just had it towed to my local Porsche specialist.
Oh and the engine number does not match the COA. Looks like an engine swap at some point. Guess my auction steal was not so much.
Oh man, that sucks. Post the engine type and number. If it were a Carrera 3.0 it should be a 930/02. Located on a flat portion of the engine just below the engine number.
