I had a 76 280z in about 1984 -1987 ,it was not rusty but it came from BC ,I spent a ton of money buying special parts from Bob Sharp Racing who had a great history with z cars ,Hemi head ,Porsche fuel injection pieces ,Koni suspension ,recaro seats ,exhaust ,real Carrol Shelby pin drive wheels ,and Firestone police pursuit tires which were hard to get around here at the time .Its common for the paint to crack near your quarter panel seams above the quarter windows (sorry I don’t remember exactly the spot but right in that general area ) so make sure you finish that area good and strong (actually google should show it and possible fixes ,it was very common ) .They are really tough on the chin spoiler as you couldn’t judge the front of that car very well .It would easily cruise @ 160mph in 5th ,but would get really quick if you dropped the hammer . Thanks for bringing back some wonderful memories .I sold mine to my brother when I was in the army ,he sold it a year or so later and a year after that the police called him to get it out of impound ,I guess the new owner never registered it ,and we were too honest to go get it back ourselves . There was also a body kit from Joe Alphabet in the 80’s to turn it into a Ferrari Daytona look alike ,they used one on the Miami Vice TV show .
