I don't mean any offense, but have you tried searching the "Interior" sub-forum using those keywords? There are plenty of threads discussing those exact seat installs, which should hopefully give you more than enough info. Not sure what year your Z is, but there's another 'seat swap' list that's specific to 280s (and late '74 260s), unique because of the reduced lower width due to the bulge in the trans tunnel to allow space for the cat converter. You can find that thread at:

Hope this helps, and be sure to post your results as well, after you've completed your swap. Thx, and happy motoring!
