Points to Electronic Distributor
There's a few things im willing to make an exception on being not original, one of those being the points ignition. This stemmed from me trying to set timing using the points dist. and learning the system relative to electronic, was "unreliable"
There's a lot of info out there on the topic so ill just add what i did a bit differently.
The main goal was to keep it LOOKING stock. No rouge colored wires, extra boxes, brackets ect...I esential just reused the entire stock wiring system, gutted the resistors for the coils and jumped them out internally to maintain the factory ring terminals. i then just repinned the stock distributor signal wires and added the two extra wires and loomed it up (or something like that)
Before with stock points distributor
testing it out
Part store 12v coils
my custom harness with OEM plugs
gutted the resistors to maintain the 12v
Shhhhh they will never know
All finished up
Bad photo angles but it looks and runs great but most importantly timing adjustment are consistent now and spark is strong.
So now with the Fuel and Spark right on the money the car is running like new. With that said, i'm not to familiar with how the plugs should REALLY look but i think its running lean. These were new plugs after 50-80 miles

Thanks! The coilovers are awesome, totally changed the handing and feel of the car for the better all around. the only "issue" i've had was running the car at max low in the rear would cause the rear suspension to be audibly unhappy and bind the T3 drop brackets in the rear help with this but not compleatly. raised it up and inch, match the front to tthe rear and it rides and corners awesome.
its current ride height

Great job on your car. I like that you're keeping it true to original. For future reference, the trim color in 79 was more of a metallic grey. Wasn't until 1980 they used black. The 80 trim is on top in the picture and mirror on the left. 79 trim / mirror are on the bottom and right.

Also, a good method to refinish the windshield trim is to use a vinyl wrap instead of painting...no need to remove the trim and break the little plastic clips. And it's more durable to the little stone assaults compared to paint.

Custom FC Fan Clutch Adapters For SA
I made it my mission for the beginning of this year to fix my stuck/seized fan clutch once and for all as it was so loud and even with dual belts and proper tensioner managed to shred belts above 3500 rpm.
After seeing a few unsuccessful rebuild attemps on the 79-85 stock fan clutches (mine even has a phillips screw/port on it already..interesting) i opted to raid my brothers FC pile (again) and snagged his fan clutch.
My 79' fan bolted right up to the clutch, but the clutch wouldn't fit the engine, a few machine tools and attempts later and i was left with this.
It was tricky maintaining the stock thread engagement for safety, along with actually making it fit.
I was really aiming to make these a 100% bolt in part but there were only 2 complications..one of which being i had to ditch the 4 original m6 hex heads that held the adapter to the water pump for socket head ones so they didn't interfere. Along with small trims to the fan itself that can be seen in the pictures of me holding it on the outer parts which was just contacting the shroud.
The difference fixing the fan made driving the car was night and day, i could go on all morning about it but i can finally hear my exhaust again without tuning out the squalls and squeals and i seriously think it picked up a HP or two lol. This should also make checking the timing @5000rpm after the distributor upgrade less frightening
Now i'm not a full blown shop, but I did an extra run of adapters for anyone reading here that may want to do the same with a FC fan clutch for their SA ( maybe FB) and refuses to go E-Fans. Just shoot me a PM or email. I'd also be willing to send or post the blueprint I drew/used for those with that want the full experience
