you've deffo got post 92 granada calipers

or even the mondeo V6 ones for the mk2 if romours are to be believed

measure the inside bit of the piston as this may give you some idea of what they are, but seal kits are cheap as chips, you only have 2, one inner fluid seal and one outer dust seal so as long as you don't use the words "cosworth" you won't get taxed on it as such

i've got loads of them floating about so if you give me the measurements of the inside i can go and check with mine, preferably using vernier calipers rather than an old plastic school ruler though eh
