Clutch servo or diaphragm

[gejtu22]

My 1302s stickshift is sucking air through the clutch servo because the diaphragm is damaged! i have to get a replacement part cos the clutch is not cutting in and is undrivable.

I consider replacing the diaphragm or the entire servo. Can anyone help please. in Malta an autostick is extremely rare and no parts whatsoever are available.

i have a manual gearbox at hand, but would hate to have to use it.

Thanks for any help!!
