I would use Rubber Bushings for An Imperial ride. Outer Tie-Rods and most front end parts should be available fairly easily. Inner tie-rods will be expensive. Rare parts and Kanter could be a good place to start.
I have a 65 Imperial convertible that I've been thinking about doing something with for many years. The fellow that started this string for information, if he is like me and on the "Cosmic Calendar" as well. Time slips by and sometimes these parts searches go on for a log time....Good Luck to all of us...!#!
