Fabia 1 door lock repair kit

Hi Again,

Have got my repair kit via Ebay

Can i ask, is there a clear illustrated guide i can follow on how to do this ?

I have removed barrel from car, but i am not sure on orientation of spring or indeed how you get the spring back together, sore fingers so far, are there any tricks to this please.

would appreciate your help please

I did have the previous barrel fitted by main dealer, on taking out this morning, have found the top screw is missing, they must have dropped it, just held now by bottom screw, anyone know where i can get replacement screw ?

Thanks in advance
