Hi guys. I hope some of you can help me solve this problem - I have a
mystery rogue clutch master cylinder on my 87 E28 520i. The design and
fitting is totally unlike what should be there, at least according to my
local BMW dealer. The cylinder is FAG Part No S5392A. Now I need to repair
or replace this cylinder, and I have no idea where or how to get a
replacement........!

See my note below, which I posted a few days ago.

"I have to change my Clutch MC, and according to both Haynes and my local
part provider, the one that is in the car is all wrong. It has a 2 hole
mounting flange set at right angles to the axis of the cylinder and bolts to
the face of the bulkhead. Whereas Haynes indicates that it should have a
flange face parallel to the axis of the cylinder and bolt to a plate next to
the clutch pedal. Did they change the design in the last year of E28?? What
is going on?"
