Well So far I only have the passenger side done. It was pretty straight forward. I cut the stock 350Z mounting tabs off the rails, cut off some other bracketry , Welded crossmembers on, took my stock seat rails off and apart, Mounted them in there stock location. Then I set the 350Z seat in place measured everything to make sure I had enough space for movement forward and backward. I tacked everything in place then took it all out and welded everything together. Then applied a couple of quick coats of black.Nex interior change will be a new black carpet kit! Heh I figured heck while the car is down I will go ahead and tackle this little project.
