Good effort there, I can relate to the sentimental value and enjoyment of doing it yourself. Although not in the same bracket you have to look at the dedication and work people put in to restoring Mk1 & 2 escorts, so it's entirely your choice.

Is it the front floor sections you need or what parts exactly? Can you post photos? Your other alternative is to find someone breaking a car and see if they'll cut part out for you. New panels can be had for anything, it's just a case of time and money waiting for them (and knowing where to look).
