Urgent Help needed...Clutch Master Cyliner - 2000 TD5 90

Hi all,

Clutch Master cylinder has just gone kaput! I have an unused Lucas
one for a 200Tdi - Are they the same?

From inspection they look the same barring the electric bits, but
these look as though they will just screw into the tdi one??

Any advice please, i could really do with the motor back on the road
in the morning.

Thanks
Jon
