I've been donated a pair of 2WD Sierra Cosworth 4-pot calipers but it looks as though the mounts are difrerent to standard Sierra hubs.

Are there adapter plates that can be fitted to mount them ? ?

Loads of faffing and grinding to bodge them on to fit -

One of a few threads on the matter,

I went to 283mm cossie discs using original calipers

yep, as the reply above, tried it on the old rally car and quickly got the cossie uprights to go with the calipers, std ones don't go.

Never mind, got them as a freebie anyway.....
