yes.. there are many ways to do it... Some part numbers are shared however, so that would need to be noted.
I think the FAQ is a great idea too .. will require some research.. and time to massage into a comprehensive resource, but when its there, will take out much of the traffic and frustration out of the forum. The same things get asked over and over, and are all available in older threads. It just takes somebody to traul through and decipher all the crud out.. and you have a great resource.
Since I thought of the idea about 50 questions have already popped into my head that could be answered in a short paragraph each.. You'd break it down into sections so you'd have "classic skylines", R31, R32, R33, Stagea, etc and as much "need" to know information as you fit in each. Like "what is the difference between the 4 door R33 and 2 door R33?", "what is required to fit an RB26dett into a RWD?".. you could even have a parts locator service (names numbers in each state).. man the list goes on!
