Hi don't know how far you have gotten with your strut overhaul, but after having done it recently, Im in a position to point a few things out!
You are right in searching for new strut tops - when it comes to suspension/steering, I have found out (the hard way), it is often a case of replace it all or not at all!
I have fitted the spherical bearing strut tops avail on SMCKA's website and yes they do raise the height of your car by 1 inch! This is because the manufacturer (GRP4 in Ireland) originally designed them for the cortina. I guess the cost of remodelling up a similar unit for the escorts have just made our life a little harder! They are however great units and I am very happy with them. I am about to purchase -2 inch springs to get my ride height back to the -1 I was at! Otherwise you can go for the Eurospeed or K-mac options available, but they are much more expensive!
All the best!
