9" rear donor database

I have been out of the loop for a while with other obligations but now i have a little free time. I'd like to build that 9" donor database that a few people asked for. What fields do you guys think I should put in there besides the obvious,
  1. year
  2. make
  3. model
  4. donor car year make and model
  5. comments
  6. disk/drum
 
You might want to add the stock information as a header for each year that way you can see at a glance what if any differences there are from the original stock setup.
 
A rear end from any cougar (67-73) will bolt right into any mustang of the same year. if you want to get real swap-crazy you can use a 68 cougar rear in a 67/69/70 Mustang, and a 72 cougar rear will fit a 71 OR a 73 Mustang.
