I have been told that the easy way to join a Zetec to an MT75 is to use the stock 2ltr flywheel/clutch and a Westfield clutch release bearing.
Westfield modify what I am pretty sure is a stock ford release bearing by extending it to give you the right amount of travel.
The big shock is that they charge £50+VAT for the little bugger!!!! 
On the off chance, any one has one of these bearings that they can take some photos of or take some dimensions from I would be eternaly grateful.
Thanks,

Obviously I'm not advocating this approach, but if you reverse the friction plate so that the slightly longer boss faces out towards the release
bearing, this is an equally useful solution.
This means that the springs which cushion clutch take up are rendered useless, but it never bothered me or the susequent owner who raced it for the
best part of a season after that.

If it is a modified bearing, and you can get the dimensions and the type of bearing (probably a ball bearing) there is a place near Huddersfield called HB Bearings who can make one for you - probably cheaper than Westfield, or they maybe make theirs!
Why not just use a lathe to machine a spacer??
Cheers
Not a lot of help but Dunnel supply a clutch which uses a standard release bearing from Sierra MT75 setup. They say they went down with this road as the Westfield ones were not that reliable. Which clutch they use I do not know.
I have a similar problem. I ahve a Cosworth 24V V6 fitted with a 2.8 V6 flywheel.. And an MT 75 2.9 V6 box. the 2.8 Fly is a few mm Thinner than the
2.9 one and makes the release marginal. So I need a longer nose bearing..

You've got me bang to right guv. I was talking B**locks.
We definitely reversed the friction plate, but the mists of time now leave me totally at a loss as to why we did it. Clearly, you are absolutely
correct in that it has no influence whatsoever in the action of the release mechanism of the clutch.
I should probably be ignored from this point onwards. 
Did someone say something
TT
Oi - I resemble that remark
Maybe we did it to get rid of the protruding boss which then hid in the well in the centre of the zetec flywheel.
In fact, I think this probably was the case.
I'll shut up anyway......grrrrrrrrrrr
Just use a Capri 2.0 release bearing.
This bearing is longer.
Its partnr. is 500 0071 10 fom LUK, i think.
But if you want to be sure, talk to Mave (www.mk-indy.nl). He used this bearing in his MK-indy.
you can use this nr. to get it from Borg&Beck or some other manufacturer.
Would love to know if that's true

Mave has used this bearing to mate with a type 9 not an MT75.
I have been told that the parts required are different.
I would love to just turn up a spacer but I really need to see the westfield part to see how they have done it and take some dimensions.
I can probably make a couple if anyone else need one?
You could take the dimensions from the Westfield one and try a bearing distributor to see if it is a standard part - would be relatively cheap then even if not a common automotive part. Trouble is, someone may need to buy one from Westfield to get the dimension - alternatively the standard part dimensions with the required width may be able to be matched by a good distributor.
Yup.... and I think I'm gonna have to be the one to cough up for one from Westfield!
Take a look at Westfields online catalogue here
Release bearing
You will find a picture of the bearing at the bottom of the page.

It is just a standard bearing with a spacer bonded on (i think they use hot glue or araldite). I've got one fitted to the zetec/mt75 combo in my
Westfield.
I'm going to be binning my mt75 in favour of a type 9 as i'm sick of a clonking noise + the release bearing really rattles which is a
feature of it (according to the Westfield forum).

Decided to try and scale the dimensions of the spacer from the westfield catologue photo.
I will turn one up and bond it with blue arraldite (long set, extra tough - especially when you cure it in the oven) to a standard Mt75 release
bearing. By the looks of it, that is what westfield do but they charge you £55 quid for it!!!!!!
My questions to you are:
Other than maybe weight is, there any reason why the spacer could not be solid in the outside?
Is it shaped like this on the outside for some specific reason or could I just carve some metal out to save weight?
Cheers,
DC
