During some extended hard driving the original clutch in my '79 finally gave up.

I got the Sachs power clutch installed but was tolld to bring a new clutch cable ASAP. So that's now on the way.

In the meantime, while the clutch pedal is much easier to engage, getting the car into 1st gear or Reverse without grinding the gears is a challenge. In fact, 2nd gear is now a little jumpy at low speeds/revs, and it never was before.

So my question to you guys: could this all be due to a bad clutch cable? Perhaps the new clutch requires adjustment?

Thanks, All!!

Old clutch cables stretch and when you run out of adjustment you are changing gears while still partially engaged (grinding, nicking and hard throw). Remember it is not hydraulic but fully cable operated.
When you put a new plate in it took out some adjustment from the old worn (thinner) disc and you don't have enough adj on the cable to work with.

Phew!! I was terrified it was the gearbox synchros, but didn't understand why this would be an all of a sudden issue.

Hopefully the new clutch cable will fix it!

Thanks!!!

It will.

It's 'all of a sudden' because the old disc was so worn it gave you that extra few millimeters of slack that equaled more adjustment.
You'll be fine with a new cable.
If you are putting it on yourself pm me and I'll give you a tip.

there is a procedure to adjusting the clutch cable... also, shift bushing and coupling may need attending to.

Yeah but don't follow the factory clevis setting for the GEMO brand. They are excellent cables and OEM for Porsche now but they are a tad long.
Wind the clevis down as far as you can then set the nut. If you follow the factory depth you'll already be out of room on the tranny cable end.

Or trade up to a G50 car.

Well a g50 will go shot also. It was end of life and is rebuild, cost a fortune, but very good now :-)

Mine is very cold blooded. Once warm it is super smooth. Cold, it hesitates or requires a little more effort and patience when down shifting. It's a price I'm willing to pay.

Yeah, G50's are great boxes for unskilled operators with deep pockets.
