V6 (ES9J4) clutch cylinder

[gyufa]

Hi Guys,
I'm new to this forum but I need a little help w my Peugeot 406. I hope I'm at a right place!
So my car is at the mechanic right now as I had a problem with a clutch (pedal to the floor, and it doesn't work at all). It turned out that the clutch cylinders (master and slave) need a replacement - so far it's fine.
My problem is that we cannot get the replacement parts... The mechanic has tried several aftermarket parts, but they didn't fit. Original part is not available anymore...
Could anyone help me, does anyone have a spare clutch cylinder? I'm attaching a few pics about them.

(The car details: V6 - ES9J4 engine, 1998, it's a 406 Break, but this doesn't really matter I guess.)
Thanks!

If you can't find one in a breakers yard, I'd suggest seeing if you can upgrade to the separates system used in 1999-on 406s. Last time I looked, the cylinders could be bought from ECP or dealers for about £15, but you'd also need a new brake fluid reservoir and the pipework which might be harder to find

Don't know if it's any help but I have a 99 406 coupe 3.0 V6 ES9J4 it has a blead nipple on the system
So you should be able to retro fit it as we have the same engine.

Sorry I can't give more info tonight,
Failing that try BB Autos in Chesterfield they break a lot of 3.0 V6 coupes & send stuff abroad

Thank you for the hints!

In case I would change the system to the new one, which brand should I use? Which one means the less additional work?
