I know that there were some changes from the series II to series III Z's, including a new tranny design and the rearward movement of the rear end by 35mm. What I do not know is what all was included in the movement of the rear end (as far as mounts, suspension, brakes, etc.) and what improvements were made to the tranny.
I am considering buying a clean '71 with a '72 parts car. I want to eventually use the car for autoX/track days, and am interested in making a great handling car. I have been looking for a rust free '72, but this '71 looks (from pictures) pretty decent.
1.) What parts were moved in the switch to the series III cars? How was the trans revised or improved?
2.) Do the improvements made to the Series III cars make a noticable difference in handling/driving/maintanence?
3.) How much work would be involved in swaping out the noted '72 parts into the '71 to effectively make it a series III?
4.) Would it be easier, or would I be better off, to just wait till I find a really clean '72, rather than building a '72 out of a '71?
Any help with these questions would be much appreciated. I have not went to look at the cars yet, as they are about 3 hours away. However, I would like to know what to expect when I get there. Thanks!
