OK, here's what I think I know so far. The cleaner intake is indeed a Machine intake. The dirty intake MAY be from a '70 Javelin. The ring & pinion appear to be my car's original 3.15 pieces, as the numbers stamped on the shaft match the item number on the window sticker. Thus, I believe my car currently has a steeper set installed. I'll jack it up tomorrow and find out...but I'm guessing 3.54s. The Performance American Style book is a 'second edition' but not the later reprinting of the same. The blue and black color separations inside are very different, plus the cover displays the original $2 price. The Chilton 68-71 AMX & Javelin manual is long out of print. I recall looking around for one with no luck years ago. Still- any and all help is appreciated. Take a look at the pics and let me know. Thanks. http://au.pg.photos.yahoo.com/ph/jwramc/my_photos John
