Firewall is identical.
Even the indents where you need to drill the holes are there.
The firewall is pretty weak in that area though, so you may want to look into bracing it or reinforcing it somehow.
I didnt when i converted my NA to turbo hydraulic clutch and the firewall was flexible, affecting the pedal feel...and eventually cracking. I then had to reinforce the whole area.

Look up only944.com, you'll see what a firewall brace would look like.

It is, you need the complete 944/931 clutch pedal assy as well as the master/slave cyl....also you need the 931 bellhousing and probably the clutch as well.
944 pedal shape is also different from the 931.
Good luck.

Ah, haha well then you need more stuff.
The master cyl is located on the LHD side like on the LHD cars, you just get a long connecting rod that is linking the rhd pedal assy with the lhd master cyl.
Its how the factory did it. Have a loot in PET.
I’ll try to find some pictures later but open the porsche parts catalogue and you’ll see there exactly what parts you need.

Morghen....that's for the brakes.
Clutch master on RHD cars is on the RHS. Pedal acts on master cylinder through the firewall, with the fluid reservoir sitting higher attached via a flexi hose to the master cyl. Fluid from the master travels via a hard line to the slave cylinder mounted high up on the left side of the bellhousing above the starter motor.

Doing the conversion on early (76-79) is different than later where firewalls are identical. I just did the conversion on my '78 CGT project and it required much more work compared to my '83 that I did like 10 years ago.
You only need clutch pedal not the entire assembly since with early car you will not be able to retrofit servo system anyway. On later 924's you can.
