I have answered this before, so I am sure the info is out there.
A friend has used a TA22 slave cylinder on his JDM T50 for years. And I believe T18 (79-83 I believe, though Google can confirm) will be the same. A quick part number check at Repco will confirm that.
And let Repco/Bursons/elsewhere find the part number for you. If they are so useless that they mess that up then shop elsewhere.
