One last question if I may? I see there are different depth throw out bearings so how do I know which size I will need? I have a Borg Warner Super T10 4 speed and I have just ordered a clutch linkage set up for a 57 including the fork.

Trannie is a non factor a super T-10 or oem 3 speed same TO bearing. You need the one that matchs the clutch & PP.
I believe the diagram clutch uses the short bearing and the three finger, spring clutch uses the longer one, but double check to be sure.
I think Richard had a typo.. he meant 'diaphragm' ? and I think the other type (3 finger) is called a 'Long style'? Not sure which TO bearing goes with each though...
I alway thought a 3 finger in GM was a Borg & Beck, the Long style was Ford thing.
That would be correct on the Long style vs. Borg & Beck. B&B uses a short throwout bearing as does a raised finger diaphragm. A flat diaphragm (which was the original clutch in a trifive) uses the long throwout bearing.
A Long style is sometimes used in GM products for racing/high performance applications. It is superior to a Borg & Beck because a B&B has rollers which add clamping force as rpm increases, and these can stick. A Long style can have weights on the fingers which also add clamping force with increasing rpm and they do not stick. The weights are usually bolts and nuts and add a bit of adjustability to this feature. I am not sure on the throwout bearing - it might be "medium" length, at least sometimes.
The pressure plate cover for both B&B and diaphragm clutches have a symmetrical 6 bolt circle pattern for attachment to the flywheel. The dimension of the bolt circle varies with pressure plate size.l The pressure plate cover for a Long style has 6 bolts but the pattern is 3 pairs. It is a special pattern that most flywheels don't have. (Can be added or special ordered though.)
I really thought the 3500 or 4000 pound roller assisted PP that I used to run in my 67 Camaro 40 years ago was a B&B. I still have the Competition Engineering firewall brace on the car that was necessary to prevent flex. Obviously, my memory is fading on this one.
