Hi All,

I'm currently having my 1990 Sapphire Cosworth 4x4 gearbox rebuilt and have discovered the rubber doughnut is knackered. Its the early, thicker type.

I've done a bit of digging and, as usual, the part hasn't been available for some time. The only solution to enable a new, thinner, later type doughnut (1992 onwards - and readily available) to be installed is to swap the output flange and maybe a couple of other things including the front section of prop shaft also from the later Sapphire Cosworth/Escort Cosworth.

Is there anyone out there that has acutally done this mod and can tell me EXACTLY what I need to get and do to make sure this works?

Had lots of people give opinions but nothing solid. Any advice/guidance would be gratefully received.

Alternatively, if anyone knows of a solution/alternative part to replacement, that'd be awesome.

Many thanks.
