Can anyone recommend a source for the above? Some car or other must have a pull-type slave as standard?

Rally Design sell the Wilwood one, but seems a bit pricey. Linky to Rally Design

Can't say I can think of any production car that uses a pull type cylinder however ISTBC

Citroen Xantia 2.1 Turbo Diesel

The Mazda RX7 FD3 uses a pull clutch but with a convenional slave, just reversed so the clutch fork plls the pressure plate instead pushing it.

I dont suppose its much help though

Those Wilwood ones used to be cheaper before the $/£ rate went down the pan...

It's the only solution I know of bar fitting an internal concentric slave cylinder (and a Ford box conversion isn't cheap - about £120 from Burton power)
