So, I finally figured out what seats came in my 240Z. Twas a long and difficult road since the parts numbers were as generic as generic can be. Anyhow, they are out of a late 80s, early 90s BMW 325i. Lots of adjustability, but require seat mount mods. The PO rigged them up with some plate and two part epoxy (lol) but as I am repairing my floors and frames, I will weld it up proper. Pics!
