Anyone know what'll fit?

Application lists from lead manufacturers such a Lumenition / Splitfire / Magnecor, etc list lead sets for the Ford Ka with the same Endura E lump under the bonnet, but don't say if they'll fit the Fiesta as well (e.g. same length, different fitting at one end).

I was thinking of the Lumenition ones from Demon Tweeks, but not 100% sure as the longest one they do (36" / 914mm) might be 16mm too short going by the measurements of a set of regular leads for my car off Eurocarparts.

Already tried to find info on this from 3 other forums since Sunday, but still none the wiser

Only had the thing since 10th April - bought with 52,427 miles on the clock and "2 careful lady owners", so still in the process of catching up with routine maintenance tasks on it that've been neglected (e.g. may have been driven carefully, had work done on it to get it through the MOT + oil changes..... but still appears to have the original plug leads + when I checked the pollen filter on Sunday afternoon it looked like you could grow a salad garden in it... haven't checked air filter yet, as I don't have the right Torx bit to get into the housing).
