Down a new rabbit hole today as I wait for the next shipment of parts to arrive.



Part of me had hoped that I wouldn't have to do much with the wiring harness, but when I laid it out it was pretty clear that 1) there was still a lot of residual upholstery glue and even some foam stuck to parts of the harness and 2) many sections of the tape had become brittle and would crumble away easily. The areas that had been exposed to heat suffered more here, but I decided that the best thing to do was take it all off and re-wrap the harness.



In the worst areas the tape came away in little tiny pieces rather than unwrapping nicely.
Luckily the wires underneath looked fine, still supple and no damage to the insulation.
I guess the wrap did its job in protecting them all these years!
I did a little wrap of electrical tape every 2-3 inches as I went so the wires would stay bundled neatly.



I re-wrapped the harness with Tesa 51036.
This is the high-heat abrasion resistant automotive tape used by VAG and other OEMs today.
It's excellent stuff.



On areas where heat is not an issue, I used Tesa 51618, which is a slightly fuzzy PET fleece tape.
This is also good stuff, and while it doesn't have the toughness or heat resistance of 51036 it has the benefit of muffling noise if wires vibrate against something else in the cabin.

My big delivery for today was pushed back to Monday, but fingers crossed I have more news to report then.

 

My third brake light wire was bad from water damage and 12v. I had to cut into mine. It was black. Rear bumper harness might also be bad. It's difficult to rebuild the car 100%. I was happy to delete defrost.
993 rear glass will be my goal. I installed the 993 front glass.

 

Monday's delivery should include 993 front glass and 993 RS rear glass. No defroster for me either!

 

Oh.. I'm jealous! Did you order from a dealer? I bought the seals but not the glass. I have a temporary early 911 glass that doesn't fit. Slightly too small.

 

Yes, I ordered from Harper Porsche. Price was good and the glass was properly packaged for shipping.
When you fit your 993 windscreen, how did you handle the correct mounting depth? I keep hearing about special 993 window installation gauges but no one seems to actually have them.


Anyway, today's fun included taking an angle grinder to some brand new Porsche parts.
I simply could not get the inner frames to fit into the RUF mirror housings, no matter how I twisted them.
Eventually I sent an email to my RUF contact outlining the problem and asking if I should just cut off the part that goes down into the 'arm' of the stock aero mirror.

Yep - turns out that's what they do there!



Here's a before and after. Perfect fit once I cut off the offending section of the bracket!

 

These don't use the little gear that you turn through the bottom hole to remove and install the heated glass assembly?

You might try the 993 forums but IIRC the 993 windshield is like most of todays modern glass and there should be spacers that come with the windshield that keeps it a proper distance for the betaseal to fill. Any experienced glassier should know what to do.

 

Yes, they do use the little gear.
The three outer holes in that plate are where the plate attaches to the mirror.
The three inner holes are where the motor housing with the little gear that holds the mirror attach to the plate.
There are also three holes in the bottom of the RUF mirror - the oval one in the middle is for manipulating that gear with a screwdriver (the others are for the temperature sensor and the wiring harness)

 

I believe Porsche ships the small black spacers. But I installed the inner seal and handed the job over to a professional. The seal is tricky. Needs to lay perfect.
I guess I'll keep working on mine. I just bought a RS rear seat delete.
So the rear glass, you bought the one without defrost? Can I get a part number? If it's $3400 I'll probably pass.

 

I'm going to have a professional install the glass too. I've seen too many leaky 911s!

The part number is 993-545-107-07, the parts catalog lists it as for the Carrera RS. It has no defrost, no wiper hole, and I believe it is thinner glass.

Price from Harper Porsche was $1550 + shipping, so not a lot more than the regular 993 rear window.

 

Thank you. That's worth buying.

 

Not a ton of progress updates as I was away, but slow and steady wins the race.

Doors and fenders have been fitted up in order to start widening the carbon fiber bumpers.
They came with lots of parts to mount them, so first we have to figure out how all these Lego pieces fit together!



Oh... and where was I?
In a snowy field...
Where I just happened to find myself working on a 964 with a no-start issue...
That turned out to be a 964 C4 Lightweight...
Which happened to belong to some guy named Ferdi Porsche IV...
and then someone even more exciting showed up to help (ok, I became the helper when he showed up).
Surreal.

 

Fun!!!

i like the C4 lightweight. We have a couple by me.

They use Gbody signals up front?

 

Good eye. The front bumper uses G-body/930 indicators, but four of the same ones (the more forward one) rather than two front and two side.
The flat recesses on the rear bumper on either side of the slots are for the little square 930 reflectors (but the car retains the 964 brake lights).
Agreed that the C4 lightweight is very cool. Ferdi really got it sideways, so clearly having the ability to manually control the diffs makes a big difference to how the car handles.

 

C4 lightweight had more adjustability and controls than anything to date other than the 959. Might be the GT3RS of its day in that respect. You need to know what you're playing with. If only Porsche had more funding back then I suspect they would have made some serious builds even beyond the cool stuff of the day.

Looking forward to seeing the car come together.

 

Sun visors arrived today.
I believe they are based on the Cup sun visors, although the Cup cars only ran a single sun visor on the driver side.
Reupholstered by RUF in Hans Reinke Schwarz Nappa leather, but for some reason assembled with bright screws?
Luckily I have a million black stainless Porsche screws and a M3.9 tapping screw is the perfect fit.




Also checked in on the bodywork, making progress after the special 3M epoxy metal filler arrived from Europe.
This is after the first application, already looking nice and smooth.
I can't wait for all the water to pour on my head the first time I open the door in the rain!
