Front ones are a little bit (about half a winding, depends on the type of springs) longer than the rear ones.
(Early?) MK3 Escort ones had MUCH longer springs on the front. Maybe it's a MK3 set?
It could be that then. When I remove them this weekend I'll see if I can get the part number off, seem to remember noticing the number on the tops but didn't really look at them. Springs are in good condition though so hopefully I can sell them on if they are mk3's.
