For reference, My '71 has a scheduled build date of Nov. 16th, 1970, actual build date of Nov. 30th, 1970 and the block date is OK30, one month prior to actual build.
I think this helps people, very good for a DAP build (non Boss /Non 429) car!! Our cars aren't like earlier ones where 3 plants built cars and you needed to understand both demand and shipping time . (Not to mention lack of rotation/strikes and block repairs that happened to many FE's right out of the foundry!
If anything I'll bet many MANY more items will be available from "those that didn't want to sell" prior in the near future. People will start to do things differently also. Where MANY had not problem "buying AMK bolts" (so they are shinny) some will now value cleaning, prepping and plating original hardware) , which is what restorers did all along!
