Clutch advice please

[geoffp67]

Ah-ha ! thanks for your help, we may be making progress.
I hadnt thought to scour fleabuy looking at the pictures.

I havn't pressed it on yet as I'm not confident that I have the correct part. I'll squeeze it on slowly with a big vice, cushioned with a bit of wood.
The picture shows something very like my "standard" bearing, the side shown would face the gearbox as the other side is curved to rub the fingers.
The one that came with the Aisin kit is different, it looks like this one:
S14 & S14a 200SX SR20DET Clutch Release Bearing 95- 98

Does that suggest I have the wrong clutch ? Does it matter ?
I'm loathe to experiment as its an engine-out job to change a clutch on this car, and its far too cold.
