Ben,
You are correct about the ball joints and the tie rod outer ends!
Parts book: YES! There is a chassis section that is worth a helluva lot more than the body section..... I'm surprised that you ended up with only that piece! Usually it is the other way around..... The chassis section has been in reprint for years, although not entirely translated.....I've done some of the Italian and Ford part number translations where I could read them....and where they appeared in my Ford Master Parts Catalog!
I think the body part only surfaced in the past 10 years or so (may not be true!) but in my experience, I'd not run into any normal owners having it.... Doesn't do you any good anyway as it is written differently than the chassis book, which has parts "sources" listed....as to who was the supplier and perhaps manufacturer, which does come in handy! Even sometimes model numbers of specific donor cars are listed.
Check with Larry Stock, he should have the chassis parts book in stock. (Pantera Parts Connection in Reno)
Ciao!
Steve
