Any pics of the one you are using ??

I swapped my old Granada one for a Subaru item from an Impreza turbo. I think from a 99/00 model. Only difference is outlet pipe configs and reservoir shape. Although I think all the earlier ones have a taller round reservoir. Mitsi Evo's are pretty much the same. Typical 4 bolt fixing.. If you cant get one locally, stick a wanted ad up here

One of the guys will defo have something.

Should be easy and cheap to get hold of....pretty straightforward fit. Send me your email if you want more pics...

I've got a brand new ford servo if you're interested. Sold to me as Cortina V but I'm not so sure of that (thought they were same as cortina IV). Mounting bolt pattern is same as Cortina IV but mounts for master cylinder are slightly closer together. Get in touch if you're interested.

Diameter of this servo is 228mm and the thickness (mounting face to mounting face) is 93mm. The distance between the studs (centre to centre) to mount the master cylinder is 62mm.

The pushrod to join to the pedal is 225 mm to the cenre of the clevis pin hole.

The four mounting bolts on the rear are 89.5 -90 mm "square"

Yes - My Cortina IV (same as Capri) has a smaller diameter but is fatter. However the spacing for the 4 mounting studs is the same and the Cortina/Capri master cylinder will fit with only a small alteration to the mounting holes.

I only posted it up in case you have any difficulty getting replacement bits

The Subaru one pictured is also smaller diam and hight than my Granada one.

4 bolt holes have a slightly smaller PCD...but it was an easy fit onto my Granada bracket, and easy to hook up to the pedal.
