Doh!
Isn't the clutch release arm (that holds the carbon bearing) different on the 948 due to a different distance between the pivot and the forked ends on the inboard end...or am I being thick?
In the back of my mind is a memory of having to pull out an engine again due to.... :oops:

Not sure about the arm - but the 'plate' is different 948/1098.

On a manual clutch setup the gearbox front plate, forks and thrust bearing are different from 803/948 to 1098/1275. The 1098 front plate would be different RHD to LHD but the forks and thrust bearing would be the same.
Just a thought but would a 1098/1275 front plate for a RHD hydraulic clutch be the same as a front plate for a LHD manual clutch?

Update> I have just phoned John Evans to check and he has confirmed that you can use a hydraulic clutch front plate for a LHD manual clutch and he can supply the correct forks and thrust bearing. He also said that there is a hole for the clutch linkage return spring.
His phone no. is +44 2392 465256, mobile 0777 638 1520

I must be confused...upon swapping a Midget trans for my smoothcase, I had to exchange the front plates precisely because the RH-exit midget plate would not suit the LH-exit mechanical setup. Sorry if I'm being thick.

Yes - you would have to - but did the plate from the smooth case box fit directly onto the 'new' box - and was it a ribbed case box?

Roy,
I did have to modify the smoothcase plate to fit the ribcase. The spacing of the holes for the studs is different in two instances. I had to drill one new hole and make the other slightly oblong, if I recall correctly. If I had it to do over, I would probably have tried to work out a hydraulic arrangement and left the plates as is.

Ahh - good - all explained then! And I don't agree - the mechanical clutch really is better than messing about with hydraulics - when the car doesn't have a master cylinder already.
