Right the hole centers on the Fiesta seats are 310 x 560 (back brackets)



The 'scort runners will need a bit of an adaption, they have abracket on the front that is riveted on, that will need to be removed and by using the front rivet hole as a mounting hole the dimentions will be 310 x 455 (back bracket) now the second dimention is not relivent because the width will be changed when you bolt it onto your new seats, but the bar indacated on the pic below will need to be re-made as it wont be lond enough but that shouldnt be a problem.



Hopefully this will work can't see why it wouldn't, I fit a pair of Cobra Clubman seats into my last Mk II XR2 with Peugot subframes and Fez runners.

And alos fit a pair of Mk II XR2 seats into a Mk III Fez, so anything possible

Keep us updated, would like to know if it works.
