9" fitment chat ???? Should I create one

Should I create a 9" fitment chart ? I had one person ask a long time ago and another ask recently for one. It wouldn't be a bad idea but I'd like to get some input. The obvious fields such as your car, year, would be in there plus the "donor car, year", driveshaft, would be there. What else should I include ?
 
I think it's a great idea. It would/should help cut down on some of the posts about 9".
How about a field on what mods had to be done to make it fit? Where did you find the rear end? i.e. bought brand new, junk yard, ebay,
