I guess the solution to all this is to use the SIII pressure plate with the SIII throw out and the SIIa 3 finger type on the SIIa.
However I seem to remember that the difference between the 3 finger type and the diaphragm type is not anything to do with spacers but that the diaphragm type is for a 9 1/2" pressure plate while the 3 fingers are for the 8" (or 9" no books at work) and the spacing for the throw-out sleeve is the same whatever pressure plate and throw-out you use.

As I said in my first post, that is what I did on my dad's IIA.Quote:

It has been working fine since 1997. I suspect it has work a bit, as the clutch linkage needed adjusting once, but it is still hanging in there.
IRC it was about 16.5mm thick. We had a IIA and SIII gearbox side by side so I just measured the difference.
Yes and no. The SII/A/III were fitted with 9" and 9.5" clutches. 9" went in the petrols, and 9.5" in the diesel and one-ton models.Quote:

The IIA 9.5" pressure plate had a disc in the middle:

The SIII 9.5" (and 9" if used?) had no disc - basically identical to above, but the lack of disc means the clutch mechanism either needs 16mm extra travel or must be 16mm closer to the pressure plate.
