Vocky will probably be your best bet for this answer but I believe that the cylinders are the same for both cars. The slave cylinder would need a spacer behind it so that it makes contact as it would stop short if used with a single mass flywheel.
See below, this is a post from Neils thread about the modification he made for fitting his lightened flywheel to the M32 6-speed conversion which would normally run a dual mass flywheel.

the M32 box is designed for a Dual Mass Flywheel puke..
to use a normal flywheel a spacer needs to be made for the clutch slave cylinder :roll:
the M32 has a distance of 59mm between the mating face and the slave cylinder, the F23 has 47mm, so a 12mm spacer is required 🙂
thanks to Luna_s for measuring the F23 box cheers..
I also had to machine a slot to allow the clutch slave cylinder to sit flat on the spacer and use some longer bolts 🙂
the fitted spacer.....
