I am looking at ebay item # 200631596549. It is a 1977 280z. Can someone let me know what they think of picture #22- it looks to me like the chassis/swing arm has been modified. http://cgi.ebay.com/ebaymotors/200631596549?ru=http%3A%2F%2Fmotors.shop.ebay.com%3A80%2Fi.html%3F_from%3DR40%26_trksid%3Dp3984.m570.l1313%26_nkw%3D200631596549%26_sacat%3D%26_fvi%3D1&_rdc=1 Thanks!

I was wondering if someone could tell me what the differences are between the 280z model year 1977 and 1978. I have a 1978 280z parts car. I would like to buy a new car and want to know if I must buy a 1978, or if the 1977 model is pretty much the exact same spec in case I have to scavange from the parts car. From what I can tell the body, frame and mechanical components look the same from on-line resources. Any help would be appreciated!
