Both of those are for 56-series gearbox. And both are for 60-series. It justs depends on whether it came with a engine rear plate or not. Some years did some didn't.

The parts book says the longbed utes came w/o plate but shortbeds with. Not sure I believe that.

so i need to change the thrust bearing carrier, are these the ones out of the 56a gearbox because i think mine is the 60a gearbox short one

Yes, one for use with engine sandwhich plate, one for use without the plate

Bearing carrier might be the wrong one
I think you need one stamped "D" if you use the A15 sandwich plate
The "D" is longer than the one stamped "C"

Isent there two lengths of thrust bearing aswell? they might need the otherone??

input shaft of box jammed into back of crank and needs shortening ?

take your foot of the floor haha

could it be that your clutch fork is wrong ,this happened to me with my A14 when i put my 56A box on it ,and the clutch was slipping realy badly when my foot was of the clutch

if this is whats happening you could try adjusting the calbe or changing the fork ?

Quote:
sure that I understand.

The clutch should 'engage' when you lift your foot from the clutch pedal.
It should 'disengage' when you press the pedal to the floor.

Is the free travel adjustment correct?

I have an A12 motor connected to a 60 series box.
It's clutch is not engaging and i have my foot to the floor

installed is
A12 flywheel
A12 clutch
A12 pressure plate
A14/15 engine spacer plate

gearbox is a 60A 4 speed

can anyone tell me why my clutch is not engaging and what i can do to fix this issue?, thankyou
