    Continuing on with the 2.0 Distributor discussion which is related in part to the hard starting issue. . .I found that I am running a 70/71 911T distributor. In addition the spark plugs were a Bosch 9 and likely way too hot for the car.

    I knew I wanted to attack both fuel and spark - and with the wrong dizzy in place, I put out an ad looking for a 1968 cast iron "001" distributor. (Thank you Kjell). This is the correct distributor that would have come with the 911L, a 0-231-159-001.

    After receiving the used 001 (in great shape), I did a light disassembly to inspect and clean:

    Admittedly I love the logo/tag on here and the simplicity of the design. I inspected the internals, all was clean and moving freely. So I cleaned and lightly lubed with 3 in 1 oil, including the felt tab (even though I am running pertronix not points) and the advance setup and lower internals.

    After cleaning everything I used a two-part high temp engine paint (Eastwood) in satin black.

    I then ordered from various suppliers, a correct cap, a 7100rpm rotor, a new oem shaft gasket and a NOS Pertronix setup.

    New hardware in the mounting tab as well.

    After I installed the electronic ignition, I decided to put shrink tubing on the red/black wires to make it look a little more oem and clean on installation.

    Question for you guys. With Permatune and Pertronix, do I need a ballast resistor? I ordered a 1968 Bosch coil (As pictured) and it says on the green tag to use a 0.9ohm ballast resistor. I don't see one currently on my car (there is a solid black bosch 12v coil currently).

    Thoughts? I may not even need a ballast resistor - I found this in the Bosch documentation - but I don't want to ruin anything: "In case of breaker-triggered ignition system, use only with ballast resistor", and with permatune and pertronix, I should be able to just roll without a ballast resistor.

    I spoke with Permatune today - a great chat with excellent customer service. Apparently, the "Made in Brazil" Bosch coils cause a lot of issues with the Permatune, and it is a non-returnable part, so if any of you need the above pictured Bosch coil, still in the box, PM me.

    So, the other recommendations (none of which require a ballast) are BERU, made in Germany Bosch coil, or the Permatune coil. I have some time to research this further, but if you are in this situation - Permatune's do not require a ballast, even if the coil asks for it, because the voltage being sent to the coil comes from the Permatue module, not direct to the coil. This explains why my car didn't have a ballast resister.

    Making some progress here.

    On other news - while I sort out the hard starting issue - I decided to change the sugar scoops to a more euro look. I am usually a purist at heart, and rarely "modify" any vehicle, including the several Toyota Land Cruisers I have restored down to the correct JIS hardware, tool kits, etc..

    However, with my car already not the original color, the motor a couple hundred numbers off the original (however still an "L" motor and correct date) as well as a few modifications to the exterior (sill plates, front bumper guards, etc..) I decided to have a bit of fun that I thought would, if anything, increase the value and appeal of the car. Your opinions valued!

    Being new to Porsche, I admittedly jumped into this without lengthy research - and in doing so, found out that what I'd really like is a 1966 or 67 coupe (obviously a 67S would be the pinnacle, but $$$$). I love the green gauges, the headlights, and other tidbits.

    Don't get me wrong I am in love with this 911L. A good friend on the forum made a suggestion to me that I thought was really cool. Why not give your car a European 1968 look, similar to the 68S? I dug into it more, researched a bit and fell in love with the look. For me, it was the best of both worlds.

    Can I just add that the people I have worked with on this forum have been truly cool. I'm sure there are bad eggs out there, but seriously you guys have been welcoming, helpful and kind.

    The same member hooked me up with some euro dual bulb H1's with 007 lenses. I took to them with vigor to restore them. Apparently these headlights would have been included on European delivered 1968 911S's.

    Overall they were in good shape, but the glass was slightly pitted and needed to be cleaned and polished.

    After inspecting and cleaning the adjusters and so forth (Luckily the reflectors were in good shape, not perfect but in good shape) I took to polishing the lenses:

    As you can see, I used a Cerium Oxide glass polishing compound mixed into a paste with Meguiars "ultra cut" compound with an orbital polisher.

    I probably spent 45 min to an hour on each lens to polish the glass.

    After polishing the glass, I also buffed and waxed inside and out, making sure not to touch the inside with any finger prints.

    I then polished and buffed with the chrome rings with a fine steel wool before reassembly.

    Last, I used a silver caliper paint I had on the shelf after sanding and prepping the inner housings. (Not that headlights get that hot, but I chose the paint because the color was a spot on match and non-metallic).

    I think they turned out pretty nice. Rings are very slightly pitted/aged, but oddly, I love it - especially knowing these are originals from 1968.

    Two other members on the forum (fist bumps again) - helped with sourcing a set of euro lamps, correct for 1968. You guys know how brittle these are, especially with 50 year old plastic lenses. So, not much I could do here but polish and clean up with new bulb holders from SMC, new bulbs and replace foam gaskets as needed. Again, I actually like the aged/patina look on some parts, it doesn't distract from my liking. I drive the car, after all.

    As you guys can also likely see, the wiring is/was cut from the plug to the bulbs. These are available, but without fussing with it, I decided to just make my own, soldering and shrink tubing the electrical.
