I am new to the forum, so hello everybody

i am having a lot of trouble trying to find a throttle body gasket for my fiesta mk4 facelift 1.25 2001, (the one with the air cleaner on top of the engine). i have a plastic throttle body which i have cleaned and is now perfect and having had a new seal it transpired it was not the right one and was actually a plastic manifold seal so i had to put everything back together with old seal and surprise surprise i have a vacuum leak at the seal, a spray with carb cleaner around the join revealed this.

while its a very minor leak i am need of the correct seal. please see the picture, i have posted the link. does anybody know the part number for this or have a link i can go to? or do i have to take it up the sphincter and go to a ford dealer and pay ridiculous sums of money for a piece of rubber!

thanks in advance people.
