seattlejerry Posted March 6, 2023 Share Posted March 6, 2023 Hi All, I just picked up a relatively rust free 78 280z. My question is, if I remove those boxed sections on the floor pan that the seats bolt to, I'm assuming I'm losing rigidity. What do people typically do? I'm 6'3" and my head hits the roof Thanks!

JMortensen Posted March 6, 2023 Share Posted March 6, 2023 2 ideas for you: 1. Cut foam out of the seat. This is going to be A LOT easier than modifying the mount. I did the same on my Miata to get clearance for a helmet. Just have to pull the cover off the bottom, cut with an electric carving knife, and reassemble. The seat cover will probably be loose after. 2. Remove the original seat mounts and make shorter ones. I have done this to install aluminum race seats on my 240. The 240 has a significantly different floor pan, and I'm not familiar enough with the 280 to give specific advice, but here are some pics of what I did to my 240. I did 1" tube on the driver's side, and 2" tube on the pass side. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted March 6, 2023 Share Posted March 6, 2023 Thought I had more pics of the driver's side. The longitudinal bars are welded to the frame rails. The rest is stitched to the floor. Quote Link to comment Share on other sites More sharing options...
