Sorry, googlegroups refuses to accept any replies (or moderations) from my email at the moment so my reply is a bit late.
The early large master cylinder as you have found only fits with the early short distributor which needs it's matching ECU to work. This distributor is shorter as all the mechanical and vacuum advance is done electronically in the ECU, the later longer distributor reverted to the old mechanical advance systems and needs no ECU. The later master cylinder i think was made by Ford, or at least specifically for them. It's made out of pressed mild steel instead of cast steel or cast iron, ironically it was probably much cheaper to make. But because it's mild steel any water in the brake fluid (caused by not changing the fluid often enough, or too much pressure washing) causes rust in the bore. Silicone brake fluid is worst for this as the water doesn't mix with the fluid and instead sinks to the lowest spot and rusts. The insides of the master cylinders are completely different so, no, the overhaul kit for the earlier one won't help you. And since the probably is probably rust then it wouldn't help you anyway. Besides the distributor issue, to swap from the later to the earlier system needs the master cylinder, servo, servo mounting brackets, transfer bar and the bracket on the other end of the transfer bar all swapping over to the earlier parts. I think using a Mondeo master cylinder and servo has been mentioned before as a replacement for the later Mk2 but i've not done that conversion myself. My saloon has a Mk3 Fiesta master cylinder and servo on it but i can't remember now if i had to modify the brackets or not.
