A 314mm kit caliper in the Ebay Link?
I hope so, I just bought them... I needed a new seal kit for my drivers side and that would have been roughly the same price but with a hell of a lot more effort!
Ebay Linky - I'm not sure that model of Saab had these brake though?
Heres my 302 and 314's next to each other for comparison - Yes I know, I did clean them before fitting LOL
