Hi, I'm new to this board, and I've got a few questions (sorry if this is long!). I ran a couple of searches and found a few answers so far, but now I'd like to know: I have a '73 240z that needs a new clutch, I'd like to have a 5 speed tranny for better fuel economy, and I have a parts 280z. Is it worth attemting to swap? I know the 4 speed in the 240z is fine, but I'm not sure how the 280's 5 speed is, and my car is at the trans. shop now waiting for my decision. If you need more info please let me know! I guess what I'm asking is if it's even worth bothering changing the tranny (I've heard that the ZX trans. were the first 'real' 5 speeds), and what would be invloved, i.e. is this a direct swap, or will I need special parts, etc? Thanks so much, I look forward to learning more about these awesome cars!
