If you do disassemble to see please let us know. I have seen on You Tube where people remove the existing rubber (likely burning it out) and then pour Urethane to restore the bushing. It might be something to checkout at least for the upper and lower A-Arms. The control rod will, as I stated, likely have to be adapted either enlarging or filling the receiving hole and/or opening/sleeving the inner diameter. I'd be curious to know what modern Pinto/Mustang II parts that are sold as adaptations will work also.
As I said, I'm unsure if the rubber bushings are the same through all years. It was only the '73 steering rack I was aware of being rare. Well, that and the early front rotors. I have a vague recollection someone once mentioned that some of the later parts are adaptable to the early cars.
Unfortunately postings/replies are so light here that days, I thing a few times a week goes by before anyone responds. But there is always hope.
