yea i agree with u jmort, sometimes i wanna call these people so bad just to talk to them and try and realize why they think their cars are worth so much.
these have been brought up before, do a search on speedhut gauges and you will see the the thread is over 2 years old i beleive, i am one of those 20 and i know it was over a year ago i ordered mine, alas i dont even need them now
The diff in the 240 and 280 door is the inner support structure. The 240 door is much lighter but other than that they appear the same. The reason a 240 door wont bolt onto a 280 is because the latching system is different. However I personally have early 260z doors on my 76 280z.
