MK4 Escort front ones will fit the front of a Saff with skirts, but good luck finding them. I'm needing a set myself.

The rears are all the same from hatch, Saff and Estate. The only difference is the bracket that holds it taut to the chassis runner between the types.

MK1 rear mudflaps also fit. I have a set on my 4be ATM and they fit fine and look almost identical
