Lots of escort had quite different suspension. When I applied for K many years ago I was asked for the homologation of the 4 link rear suspension, I couldn't find it . This was never homologated as the rules in period didn't require it. That is why you see many period original cars with quite different set ups. Some have 5 link, 6 link, different spacings of the 4 links, short links and long links. Even satchel link used. Some leaf spring, some coil spring and some torsion bar.
