The Porsche 911 is a two door, high performance car that has been in production since 1963. It is made by Porsche AG, Germany. Generally, it features a distinctive design that has undergone minor changes since the original and comes with a rear-mounted engine, and an independent rear suspension. Throughout its existence, the model has been subjected to modifications by racing teams around the world, and is one of the most successful rallying cars ever made. Revered by collectors as one of the greatest Porsche 911 classics, it was in production between 1973 and 1974. RS stood for Rennsport (German), which translates to racing sport in English. The car was built so that the company could participate in racing formulae, which had a rule requiring participants to have produced a certain number of cars as a bare minimum. It featured a 2687 cc engine, which developed 210 hp. The Porsche 911 and 911S 2.7 models were built between 1973 and 1977 and had revised 2687cc engines, and more torque than their predecessors. They also featured impact bumpers, which were a requirement in accordance with US law. The 911 and 911S 2.7 models came with 2.4 and 2.7 litre engines respectively. The Carrera 2.7 cars were built for all markets, with the exception of the US. They featured a 210 hp engine, and a Bosch fuel injection pump nicked from the 973 Carrera RS. 1989 was a year when the Porsche 911 got more than a few developments, which were embodied in the Type 964. It was however introduced to the market as the Carrera 4, with the 鈥?鈥?standing for four-wheel-drive. Some of the new features on the car included a rear spoiler which deployed at high speeds, coil springs, power steering, ABS brakes, and a 3600 cc engine.
The B-pillar interior trim panel must be removed to access the release / alignment bolts. 2. Pull the belt collar trim (the small plastic part with a slot where the belt disappears into the trim) away from the B-pillar trim. The belt "collar" comes off easily and you can slide it down to the floor out of the way. 3. Pulling from top and bottom (interior trim tools work best), pop the B-pillar trim / cover away from the pillar. There are 3 small pins that snap into the pillar - one at the top and two at the bottom. But in the middle, just above the opening for the belt collar, there is a clamp that must be released by poking it from "inside" the B-pillar. Porsche has a special tool for this, which is just a handle with a metal shaft bent at the end. I found a picture of the tool shown above. 4. With the clamp released, you can now pull the B-pillar trim away, and if you haven't released the seat belt, just let it slide down out of the way.
Before we move on, just a few comments. First, if you've made it this far without breaking anything, you are doing awesome! The clips/clamps and moulding are fragile, and you might break them. But just keep in mind that the hardest part is now out of the way! You may also want to consider removing the C-pillar and rear side trim panel (directly below the window) but they are not mandatory. With the moulding and trim removal out of the way, you can now focus on removing the rear window assembly. There are only two (2) fasteners actually holding the window in place -- the rest are just guide tabs! 3. At the same time you are pulling the window towards you away from the car body, note there are a few guide pins (top / bottom of assembly). As you clear the pins from the body, begin carefully pulling the entire window assembly towards the front of the car. There is a "slot" pin at the rear of the window assembly trim that slides into a slot in the C-pillar area. This is the final point of contact that you need to clear.
If you are re-using this assembly, I would recommend wrapping it up in a blanket or towels to protect it. You should have the moulding, trim, and window assembly safely stored somewhere until you need to replace. All of the removed parts are installed by simply reversing the steps outlined above. The re-installation of the roof trim moulding is a bit difficult, as you have to get it aligned perfectly to avoid having a crappy-looking external joint near the back of the side window. I've seen a few cars on the dealers lot that look a tiny-bit "crooked" or not fully aligned. So take your time and hopefully you'll have a good time with it! When re-installing the rubber door gasket, take your time and make sure that it is slotted properly around the entire perimeter. The tricky section is the right-angle between the B-pillar and roof line. You may need to force it in a bit, but make sure it is not folded-over or creased when doing so.
