A longer bearing carrier could do the trick but it would still leave the release lever with a considerable amount of free movement before the bearing reaches the pressure plate.
How hard are the A12 bearing carriers to find?

Haha, yeah i'm in New Zealand.
A mate of mine works for a bearing company and assures me it is correct (NSK #TK40-4A for the record).
The clutch is an Exedy NSC539.
The bearing carrier moves freely on the input shaft.
I've trawled through some previous discussions and there seems to be two sizes of bearing carrier. Mine's about 44mm in length.

The car has a cable operated clutch. The engine and box are out of the car at the moment. I have taken some measurements and the bearing is physically not able to reach the pressure plate with the current setup.

Hi all,
i have been doing some work on a friends Datsun B310 that has been fitted with an A15 engine and a 60 series 5-speed dogleg gearbox. The problem is that the clutch release bearing is not reaching the pressure plate until the last couple of mm of movement. The bearing itself is correct, as is the clutch. All i can think of is that the mechanic who worked on the car before me fitted the wrong flywheel.
IDEAS?!
